East Coast Event NOT A ROCKET 31MAR09
NOT A ROCKET
by Dr. Tony Phillips
SpaceWeather.com 31MAR09
News reports that a Russian rocket fell over the US mid-Atlantic coast on Sunday evening, March 29th, are probably incorrect. A spent Russian rocket booster did reenter Earth's atmosphere on March 29th, but apparently not over the USA. According to data published by US Strategic Command, the reentry occurred near Taiwan (24° N, 125° E) at 11:57 p.m. EDT. So what were those lights in the sky over Maryland and Virginia two hours earlier? Eyewitness accounts of the Atlantic Coast fireball are consistent with a meteoritic bolide--a random asteroid hitting Earth's atmosphere and exploding in flight.

Streaking lights, explosions reported Dorchester County, Md., to the Virginia/North Carolina border 29MAR09
By Patrick Wilson
The Virginian-Pilot© March 30, 2009
Were they meteors? A comet? UFOs?
People from Maryland to Hampton Roads heard loud explosions and saw brilliant, streaking lights in the sky Sunday night.
There was no immediate explanation, the National Weather Service office in Wakefield said. The Virginia Beach 911 center had numerous calls waiting just before 10 p.m., a supervisor said.
The Weather Service said reports were made from Dorchester County, Md., to the Virginia/North Carolina border. People said they saw a streak in the sky and heard an explosion.
“It was orange, like a fireball,” said Steve Wagner, who lives in the Great Bridge area of Chesapeake and said what he saw was too close to be a shooting star. Wagner was outside cooking with family when he saw the streak. He said he went inside when his daughter called, then heard an explosion that sounded like thunder.
Chris Wamsley, a meteorologist with the National Weather Service’s Wakefield office, said there could be various causes of the explosions and lights. A team of people is looking into what happened, he said.
Lindsey Hosek of the Great Neck area of Virginia Beach was jogging along the water with her dog when the sky lit up, she said.
“The bright light at first terrified me because I thought somebody was shining a light on me, and then I saw it, and I was in complete awe because it was so beautiful,” she said.
Then she saw something that looked like a comet moving low toward the ground; it was blue in front followed by orange and appeared to be the shape and size of a refrigerator.
“It was just so low. It was like where a bird should be,” she said. “It was definitely heading downward.”
She was on the phone with a friend a minute later when she heard an explosion.
Kenneth Martin of Chesapeake’s South Norfolk neighborhood said he saw what appeared to be lightning, then the sky turned blue.
Then, he said, a white ball of fire shot close to the ground and appeared to burn out. He said he’s sure it was a meteor.
“It was so vivid in the sky, blinking,” he said. “It was the strangest thing I’ve ever seen.”
No damage was reported, the Weather Service said.

On Feb. 15 in Austin, Texas, runners struggled through the streets, midmarathon. A news cameraman covering the race happened to catch a fireball streaking through the sky.
The first news reports said a plane had crashed. A helicopter was dispatched to the site.
But there was no plane.
In Hillsboro, Rob Wesel thought he knew exactly what had happened: A meteoroid had streaked to Earth, scattering fragments -- or meteorites -- over Texas farmland.

Time to Solidify an Ocean of Magma -Lunar Study 29MAR09
Time to Solidify an Ocean of Magma
25MAR09
--- A small mineral grain places limits on how long it took the lunar magma ocean to solidify.
Written by G. Jeffrey Taylor
Hawai‘i Institute of Geophysics and Planetology
Cosmochemists are reasonably sure that a global ocean of magma surrounded the Moon when it formed. This was a monumentally important event in lunar history, forming the primary feldspar-rich crust of the lunar highlands and setting the stage for subsequent melting inside the Moon to make additional crustal rocks. Numerous questions remain about the complex array of processes that could have operated in such a huge amount of magma, and about how long it took to solidify the magma ocean. Alex Nemchin and colleagues at Curtin University of Technology (Australia), Westfäilische Wilhelms-Universität (Münster, Germany), and the Johnson Space Center (Houston, Texas, USA) dated a half-millimeter grain of the mineral zircon (ZrSiO4) in an impact melt breccia from the Apollo 17 landing site. They used an ion microprobe to measure the concentrations of lead and uranium isotopes in the crystal, finding that one portion of the grain recorded an age of 4.417 ± 0.006 billion years. Because zircon does not crystallize until more than 95% of the magma ocean has crystallized, this age effectively marks the end of magma ocean crystallization. Magma ocean cooling and crystallization began soon after the Moon-forming giant impact. Other isotopic studies show that this monumental event occurred 4.517 billion years ago. Thus, the difference between the two ages means that the magma ocean took 100 million years to solidify.

California Bolide 26MAR09
Bolide over California 26MAR09
Photo by Larry Stange- YCSentinel
Moments ago... as I was observing the Orion Nebula through my SN8/LXD (8") Shmidt-Neutonian, I saw a white flash that lit up the aperature of the scope. Upon looking up toward Orion I saw a persistant trail lasting about 2 seconds and quite long (~7 degrees.). I summoned wife to watch telescope while checking the Sentinel camera to see if it got it too. It did! A SLOW and nice Bolide with a double explosion and apparent fragmentation products clearly evident however small they are. The Fireball was heading toward the Nebula but did not quite reach it from my location 35 miles North of Sacramento.
Event Date & Time: 20090326_2108:54 PDT
Duration: 3 seconds.
Double detonation with an eye visible train a full 3 seconds after
Start Azimuth: 213 Deg., End Azimuth: 233 Deg. True North.
Start Elevation: 47 Deg., End Elevation: 32 Deg.
Second image(scaled) shows where telescope was pointed on M42.
It was only a couple of degrees elevation from the 2nd detonation point. With an 8" F4 telescope at 65X, no eye damage would have occured but only one eye would have been useful for night vision the rest of the night. :-)

2008 TC3, Almahata Sitta meteorite came from F-class asteroid 26MAR09
http://www.sciam.com/article.cfm?id=asteroid-meteorite-sudan-fireball
Rock Science: First Meteorites Recovered on Earth from an Asteroid Tracked in Space Fragments in the Sudanese desert make up an "asteroid trifecta":
discovery, prediction and recovery By John Matson Scientific American March 25, 2009
Last October, asteroid monitors at the Catalina Sky Survey at the University of Arizona in Tucson picked up a small object on an immediate collision course with Earth. The asteroid was too small to present a real threat - just a few meters across, it stood little chance of penetrating the atmosphere intact. Indeed, it exploded in astratospheric fireball over northern Sudan less than 24 hours later - anevent witnessed by people on the ground as well as the pilots of a KLM airliner- conforming well to astronomer's predictions for its trajectory. But the asteroid, dubbed 2008 TC3, was nonetheless a momentous discovery: Among the countless small objects that strike Earth's atmosphere every year, none had ever been detected and tracked before it impacted. Now the Sudan bolide has yielded yet another first:
Researchers report in Nature today
<http://www.nature.com/nature/journal/v458/n7237/full/nature07920.html>that they have recovered 47 meteorites from the object in the Nubian Desert. And lead author Peter Jenniskens, a meteor astronomer at the SETI Institute in Mountain View, Calif., says that another search completed earlier this month, after the paper was submitted, has upped the meteorite count to about 280.
Astronomer Donald Yeomans, manager of NASA's Near-Earth Object Programoffice <http://neo.jpl.nasa.gov/> at the Jet Propulsion Laboratory inPasadena, Calif., calls 2008 TC3 "a perfect asteroid trifecta,"referring to "pre-impact discovery, successful impact prediction, and successful sample return." (Yeomans did not contribute to the recovery research, but his office played a leading role in tracking the asteroid's entry <http://www.cfa.harvard.edu/mpec/K08/K08T50.html>.)
The find allows astronomers to connect the chemical composition of the meteorite to its orbit and reflectance in the sky during tracking. "The holy grail of asteroid science is to uniquely link a specific meteorite and its detailed composition to a specific asteroid type," Yeomans says."And that has now been done without an expensive sample-return mission. "This object, which the study's authors call Almahata Sitta (Arabic for Station Six, a train station in the desert where eyewitnesses saw the fireball and that served as the researchers' base camp), appears to belong to a rare class of bodies called F-class asteroids, which constitute just 1.3 percent of all asteroids. Chemically speaking, Almahata Sitta is a meteorite whose specific composition is unique among meteorite collections. It is a fragile, porous ureilite (a relatively rare kind of olivine- and pyroxene-bearing meteorite)containing graphite and nanodiamonds, among other materials. Its fragility, Jenniskens says, helps explain why it broke apart so high in the atmosphere. With the benefit of the object's rarity as an F-class body and its orbit, tracked backward through time, the researchers established a possible link to a larger F-class asteroid, the 1.6-mile-(2.6-kilometer-) diameter 1998 KU2, which may have originated from the same parent body as Almahata Sitta."The orbit of the asteroid, by just tracking it for 20 hours, is 10,000times better than anything you can get from just observing a fireball Jenniskens says. "What's neat about this is that the big asteroid allows you to extend back in time the evolutionary history." He notes that scientists might be able to pinpoint the specific region of the asteroid belt that 2008 TC3 came from with more F-class asteroids from the same parent body. Even the brief amount of time 2008 TC3 was tracked provided an excellent lead on where to look- and the desert surface provided an ideal surface for turning up the dark fragments. "The entry trajectory was very precisely known," Jenniskens says. The first samples were found in early December by a 45-person search team from the University of Khartoum. (Three scientists from that university and one from the University of Juba in Sudan are among the co-authors of the study.) "We had many eyes and hands," Jenniskens says, trying "to find these."

“Sirente crater”, Italy impact origin disputed 26MAR09
An article in journal of Geophysical Research disputes the origin of the what has been called the “Sirente crater”.The paper discussing this theory is:
Speranza, F., I. Nicolosi, N. Ricchetti, G. Etiope, P. Rochette, L. Sagnotti, R. De Ritis, and M. Chiappini (2009), The “Sirente crater field,” Italy, revisited. Journal of Geophysical Research. vol. 114, B03103, doi:10.1029/2008JB005759
http://www.agu.org/pubs/crossref/2009/2008JB005759.shtml
They concluded:
“Our data show that the Sirente crater and the minor depressions are simply the results of human activity and karstic processes, respectively.”
An article that discusses this paper is:

Asteroid Impact Helps Trace Meteorite Origins
The car-sized asteroid that exploded above the Nubian Desert last October was small compared to the dinosaur-killing, civilization-ending objects that still orbit the sun. But that didn't stop it from having a huge impact among scientists. This was the first instance of an asteroid spotted in space before falling to Earth. Researchers rushed to collect the resulting meteorite debris, and a new paper in Nature reports on this first-ever opportunity to calibrate telescopic observations of a known asteroid with laboratory analyses of its fragments."Any number of meteorites have been observed as fireballs and smoking meteor trails as they come through the atmosphere," says Douglas Rumble of the Carnegie Institution's Geophysical Laboratory, a co-author of the paper."It's been happening for years. But to actually see this object before it gets to the Earth's atmosphere and then to follow it in -- that's the unique thing."The chemical compositions of asteroids can be studied from Earth by analyzing the spectra of sunlight reflected from their surfaces. This provides enough information to divide asteroids into broad categories, butdoes not yield detailed information on their compositions. On the otherhand, meteorites recovered on Earth can be analyzed directly for chemical composition, but researchers generally have no direct information on what type of asteroid they came from.The asteroid, known as 2008 TC3, was first sighted October 6, 2008, by telescopes of the automated Catalina Sky Survey near Tucson Arizona. Numerous observatories followed its trajectory and took spectrographic measurements before it disappeared into the Earth's shadow the following day. A recovery team led by Peter Jenniskens of the SETI Institute in California and Muawia Shaddad of the University of Khartoum then searched for meteorites along the projected approach path in northern Sudan. They recovered 47 fragments, one of which was selected for preliminary analysisby laboratories, including the Carnegie Institution's Geophysical Laboratory."This asteroid was made of a particularly fragile material that caused it to explode at a high 37 kilometer altitude, before it was significantly slowed down, so that the few surviving fragments scattered over a large area,"explains Jenniskens, the lead author of the Nature paper. "The recovered meteorites were unlike anything in our meteorite collections up to that point."Carnegie's Andrew Steele studied the meteorite's carbon content, which showed signs that at some point in its past the meteorite had been subjected to very high temperatures. "Without a doubt, of all the meteorites that we've ever studied, the carbon in this one has been cooked to the greatest extent," says Steele. "Very cooked, graphite-like carbon is the main constituent of the carbon in this meteorite." Another form of carbon Steele found in the meteorite, nanodiamonds, may give clues as to whether the heating was caused by impacts on the parent asteroid, or by some other process. Oxygen isotopes in the meteorite give other information about its parent body. Each source of meteorites in the solar system, including planets such as Mars, has a distinctive signature of the three isotopes 16O, 17O, and18O. This signature can be recognized even when other variables, such as chemical composition or rock type, differ. "Oxygen isotopes represent the single most decisive measurement in determining the parental or family groupings of meteorites," says Rumble who performed the analysis. According to Rumble's analysis, 2008 TC3 falls into a category of very rare meteorites called ureilites, all of which may have originally come from the same parent body. "Where that is, we don't know," says Rumble. But because astronomers took spectral measurements of 2008 TC3 before it hit the Earth,and can compare those measurements with the laboratory analyses, scientists will be better able to recognize ureilite asteroids in space. One known asteroid with a similar spectrum, the 2.6 kilometer-sized asteroid 1998 KU2, has already been identified by researchers as a possible source for 2008 TC3. Rumble's work was funded by NASA Cosmochemistry grant NNX07AI48G. Steele was supported by NASA's Sample Return Laboratory Instruments and Data Analysis Program (SRLIDAP) , NASA's Astrobiology Science and Technology for Exploring Planets (ASTEP) program , and the NASA Astrobiology Institute (NAI).

2008 TC3 Asteroid monitored from outer space to ground 26MAR09
Public Affairs
Sandia National Laboratories
Media contact: Neal Singer, (505) 845-7078
FOR IMMEDIATE RELEASE: March 25, 2009
We saw it coming:
Asteroid monitored from outer space to ground impact
Sandians Mark Boslough and Dick Spalding watch it in real time
ALBUQUERQUE, N.M. -- Reports by scientists of meteorites striking Earth in the past have resembled police reports of so many muggings -- the offenders came out of nowhere and then disappeared into the crowd, making it difficultto get more than very basic facts.Now an international research team has been able to identify an asteroid inspace before it entered Earth's atmosphere, enabling computers to determineits area of origin in the solar system as well as predict the arrival timeand location on Earth of its shattered surviving parts."I would say that this work demonstrates, for the first time, the ability ofastronomers to discover and predict the impact of a space object," saysSandia National Laboratories researcher Mark Boslough, a member of theresearch team.Perhaps more importantly, the event tested the ability of society to respond very quickly to a predicted impact, says Boslough. "In this case, it was never a threat, so the response was scientific. Had it been deemed a threat-- a larger asteroid that would explode over a populated area -- an alert could have been issued in time that could potentially save lives by evacuating the danger zone or instructing people to take cover. "The profusion of information in this case also helps meteoriticists learn the orbits of parent bodies that yield various types of meteorites.Such knowledge could help future space missions explore or even mine the asteroids in Earth-crossing orbits, Boslough says.The four-meter-diameter asteroid, called 2008 TC3, was initially sighted by the automated Catalina Sky Survey telescope at Mount Lemmon, Ariz., on Oct.6. Numerous observatories, alerted to the invader, then imaged the object. Computations correctly predicted impact would occur 19 hours after discovery in the Nubian Desert of northern Sudan. According to NASA's Near Earth Object program, "A spectacular fireball litup the predawn sky above Northern Sudan on October 7, 2008."A wide variety of analyses were performed while the asteroid was en route and after its surviving pieces were located by meteorite hunters in an intense search.
Researchers, listed in the paper describing this work in the March 26 issueof the journal Nature, range from the SETI Institute, the University of Khartoum, Juba University (Sudan), Sandia, Caltech, NASA Johnson Space Center and NASA Ames, to other universities in the U.S., Canada, Ireland,England, Czech Republic and the Netherlands. Sandia researcher Dick Spalding interpreted recorded data about the atmospheric fireball, and Boslough estimated the aerodynamic pressure and strength of the asteroid based on the estimated burst altitude of 36 kilometers. Searchers have recovered 47 meteorites so far -- offshoots from the disintegrating asteroid, mostly immolated by its encounter with atmospheric friction -- with a total mass of 3.95 kilograms.The analyzed material showed carbon-rich materials not yet represented in meteorite collections, indicating that fragile materials still unknown may account for some asteroid classes. Such meteorites are less likely to survive due to destruction upon entry and weathering once they land on Earth's surface."Chunks of iron and hard rock last longer and are easier to find than clumps of soft carbonaceous materials," says Boslough."We knew that locating an incoming object while still in space could be done, but it had never actually been demonstrated until now," says Boslough."In this post-rational age where scientific explanations and computer models are often derided as 'only theories,' it is nice to have a demonstration like this."Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin company, for the U.S. Department of Energy's National Nuclear Security Administration. With main facilities in Albuquerque, N.M.,and Livermore, Calif., Sandia has major R&D responsibilities in national security, energy and environmental technologies, and economic competitiveness.

Younger Dryas about 12,900 BP PBS Program to Air
PBS Program to Feature Two UMaine Scientists, March 23, 2009
http://www.umaine.edu/news/view_release.php?x=1237809989
Dr. Kennett gave a talk, which included a lot of research that is either being prepared for publication, been submitted for publication, and in press. Dr. Kennett made a very convincing case that something unique, extraordinary, and instantaneous occurred at the beginning of the Younger Dryas about 12,900 B. calender years ago and could be an event that was extraterrestrial in nature. His idea that it involved multiple, simultaneous Tunguska-like events occurring across the North American continent. He also, discussed and showed pictures of the research on the Greenland ice sheet, carried out by Paul Mayewski, and Andrei Kurbatov. Outcropping along the edge of the Greenland Ice Sheetis a well defined Younger Dryas bed, which consists of dark greydusty ice with clean, white Holocene ice above it and clean, white terminal Pleistocene ice below it. They found the nannodiamonds and other alleged impact indicators right at and only at the basal contact of the Younger Dryas ice layer. They found exactly what would be expected for an layer of meteoritic debris from Tunguska-like events.
This is a show that you do not want to miss.It is in the realm of possibility, that decade or so from now, Dr. West, Dr. Kennett, and other members the YDB Group will likely be known as the "Walter Alvarezes of the Quaternary.
I am now getting together with a couple of archaeologists to do some “prospecting” for nannodiamonds and microspherules.

A LARGE rock, weighing about 100 kilogrammes fell from the “sky,” in Nkayi at the beginning of the month, shocking villagers while at the same time sending the whole district wild with excitement and speculation. The District Administrator for Nkayi, Ms Nosizi Dube, and the Police Officer Commanding Crime in the district, Superintendent Chanetsa Maswi, confirmed the incident.The stone, many villagers now believe. is a gift from God, fell with a thunderous noise in Madlilika Village in the Mjena area of Lukampa under Chief Sikhobokhobo at about 5pm on 1 March.It fell five metres from two villagers, Mr Judia Sibanda and Mr Mncedisi Ngwenya, who were herding cattle in the bush.In interviews on Tuesday, villagers from the area said they heard a thunderous sound coming from the “sky,” and another sound resembling a bomb exploding. “The noise later fizzled into a sound similar to one made by an aircaft on take-off before dying away,” said Mrs Nomsa Ngwenya, a villager. On seeing the rock fall, Mr Sibanda and Mr Ngwenya rushed to their home where they told their father, Mr Spempokuhle Ngwenya, of the incident. Mr Ngwenya told other villagers and together they went to inspect the rock, after which it was agreed that he keeps it since his children had found it.People from the area believe the rock could have been a special gift from God containing very precious minerals while others believe that it could have been sent by their ancestors in a bid to communicate something to them.
They have since vowed to jealously guard it until they get a satisfactory explanation on what it symbolises or what mineral it contains. They have been so determined to keep the rock that they even turned down Chief Sikhobokhobo’s request to have the rock.To date they have only allowed about 15 kilogrammes of the rock to be taken by the Government, through the District Administrator’s Office and security agents, so that it may go for testing. The villagers, however, reluctantly released the rock.
According to Mr Sethukile Ndlovu, a teacher at Mjena Primary School, who also comes from the area, the villagers believe that the unique stone could turn out to be something of great significance.“There is a lot of speculation at the moment but one thing for sure is that no one seems to think it is a bad omen, although people were initially shocked by the incident. A number of people touched the stone and nothing has happened to them but the strongest belief seems to be that it is a precious stone,” he said.“There is belief that it could be containing a very rich mineral while others believe that either God or their ancestors were trying to communicate with them. So, whichever way you look at it, this rock is important to the people of this area and they are keen to find out what it really is. “There is belief that the rock could be a good omen for the area and if there are any benefits from it, the people do not want to lose out.”
Mr Ndlovu said the unique sound, which accompanied the rock made some people believe that there was something supernatural about it.He says the rock was heard in the entire Lukampa area as well as Matshena, Mbuma and Nkalathi areas.
According to Mr Memukeli Khumalo, also from Mjena, Chief Sikhobokhobo sent two of his advisors to have a look at the stone. The chief also requested that the stone be sent to him but the villagers refused. “At that meeting people said they had never seen anything like that. The people refused to let go of the rock because they felt that if it was of significance, then its significance would be here. At that meeting, there was talk of raising spirit mediums so that they could find out what the stone meant but we failed to raise them during the meeting,” he said.When Chief Sikhobokhobo confirmed the incident he alerted the DA who in turn alerted security agents. The Assistant DA, Mr Knowledge Chikanga, then travelled to the area with the police last week.“We wanted to see what it was for ourselves and from a security point of view, establish whether it was of harm or not. The elders from the area held onto the rock but in the end they gave us one piece. We hope to conduct tests on the rock,” said Ms Dube, the DA.The rock weighing 15kg is being kept at Nkayi Police Station.Supt Maswi said the rock would be tested by officials from the Ministry of Mines and Mining Development to establish its chemical composition.The rock is black and very smooth outside. It is grey inside.
Contacted for comment, officials from the Geological Survey Department said they could not explain the phenomenon since they did not have a geologist in the Matabeleland region although another official said the stone could have come from space. A solid state physicist contacted last night said the object could be a meteorite that dropped into the earth from outer space.“I would say maybe a small meteorite. If it is a stone then it could be a meteorite that dropped from outer space,” said the physicist after the object was described to him.A meteorite is a portion of a meteoroid, which is a solid object in interplanetary space, that survives its passage through the atmosphere and impact with the ground without being destroyed.
According to the online encyclopaedia, www.wikipedia.com, numerous people have over the years reported sounds being heard while bright meteors flared overhead. While some scientists have dismissed the idea of sounds accompanying meteors, given the relatively slow speed of sound, sound recordings made under controlled conditions in Mongolia in 1998 by a team led by Slaven Garaj, a physicist at the Swiss Federal Institute of Technology at Lausanne, support the contention that the sounds are real.

Staten Island, NY Loud Boom 17MAR09
What Was That?
By MIKE GRAHAM wpix.com
March 17, 2009
STATEN ISLAND (WPIX) --
Staten Island residents had themselves saying "what was that loud boom" last night. Whatever the noise was, it was heard in at least six neighborhoods and rattled nerves and windows at about 7:55p.m. Monday.
Calls to 911 came flooding in and police and firefighters responded but could not solve the mystery of the explosion-like blast. Con Edison said there were no reports of transformer explosions or outages despite the fact that the noise could be heard for miles. Police believe it is possible that fireworks could be to blame. Strange doings indeed in the metropolitan area as last week Westchester and Rockland county residents reported seeing a bright yellow streak in the skies north of the city. Some theorize that may have been a meteorite fireball.

It could be heard for miles. Police and firefighters responded to numerous calls to 911, but the loud noise remained a mystery on Tuesday. Police say they found no explosion anywhere in the borough and Con Edison reported no outages or transformer explosions. Police speculated it was caused by fireworks. Last week, witnesses reported big booms of a different sort. A brilliant yellow streak was seen in the skies north of the city, in Westchester and Rockland counties.

The Near Earth Object Observation Program, commonly called "Spaceguard,"plots the orbits of these objects to determine if any could be potentially hazardous to our planet.For more information, visit: http://neo.jpl.nasa.gov/

ASTEROID BUZZES EARTH 17MAR09
Space Weather News for March 17, 2009
http://spaceweather.com
ASTEROID BUZZES EARTH: Newly-discovered asteroid 2009 FH is flying past Earth tonight only 85,000 km (0.00057 AU) away. That's a little more than twice the height of a geosynchronous communications satellite. Experienced amateur astronomers in North America can photograph the 20-meter-wide space rock racing through the constellation Gemini after sunset on March 17th. It should be about as bright as a 14th magnitude star.
Please visit http://spaceweather.com for an ephemeris and updates.
This is the second time in March that an asteroid has flown so close to Earth. On March 2nd, 2009 DD45 passed by only 72,000 km away. Measuring some tens of meters in diameter, 2009 DD45 and 2009 FH are approximately Tunguska-class objects, meaning they pose no global threat but could cause local damage if they actually hit Earth. In years past, asteroids of this size often passed unnoticed, but recent improvements in asteroid surveys have resulted in growing numbers of space rocks caught in the act of near-Earth flybys.

Astronomers Without Borders Launches New Website 14MAR09
Milky Way under the Iranian Night Sky by www.twanight.org (c)2009
Boundaries vanish when we look skyward We all share the same sky
www.astronomerswithoutborders.org
The star-filled night fascinates us all. People have gazed upward at it in wonder and awe for thousands of years. Regardless of earthly differences in culture, nationality or religion, the heavens are a common meeting ground for all of Earth's inhabitants. The boundaries we place between us vanish when we look skyward. Whoever, whatever or wherever we are, we all share the same sky.
Sharing is an integral part of appreciating the cosmos. Amateur astronomers regularly take their telescopes to public sites and invite others to join them in their exploration of the skies. The veterans relive the thrill of discovery alongside these new space explorers. This passion to share the night sky crosses international borders and cultures as well. The heavens transcend political, ethnic and religious differences. The tensions of everyday life seem to drain away before the wonder and enormity of the skies, and those standing in darkness with heads turned upward never ask people beside them about their origins or beliefs. In that moment, differences are forgotten and we are one beneath the sky we share.It is this bond between people that Astronomers Without Borders hopes to foster. A brief message or the gift of a small telescope can grow into lasting bonds, goodwill and friendships that reach around the world. Understanding replaces ignorance and suspicion. Media images are superceded by the faces of real people. Relationships, support and personal connections supplant stereotypes.
Astronomers Without Borders is people meeting among the heavens. It is only natural to do so. After all, we all share the same sky.

Forsvundet dansk meteorit er dukket op
Af Elisabeth Astrup og Morten Garly Andersen
Mange danskere i den sydøstlige del af landet observerede i januar en meteor på nattehimlen. Nu er dele af den fundet.
Dele af den meteor, der midt i januar oplyste aftenhimlen i blandt andet de sydøstlige dele af Danmark, er fundet. Det bekræfter Henning Haack, lektor ved Geologisk Museum over for politiken.dk.
Dele af meteoren, meteoritter, er formentlig fundet på Lolland.
17. januar kunne meteoren ses på himlen fra nordtyskland, sydsverige og de sydøstlige egne i Danmark.
Troede den var landet i Østersøen Ud fra de mange henvendelser, som eksperter har modtaget om meteoren har eksperter hidtil vurderet, at meteoritterne var landet et sted i Østersøen syd for Lolland-Falster.
Meteorer er sten, som kommer ind i Jordens atmosfære, og som på grund af deres høje hastighed trækker lysende ildspor efter sig på himlen.

Meteor över Skåne slog ner i Danmark
Delar av den meteor som många människor i södra Skåne, sydöstra Danmark och norra Tyskland såg den 17 januari har påträffats på Lolland, skriver danska tidningen Politiken på nätet.
18 januari 2009 Bröderna fångade meteoren på film 17 januari 2009 Spektakulärt fenomen lyste upp Sydsverige
Delarna, meteoriter, har påträffats på Lolland bekräftar lektor Henning Haack vid Geologiskt museum i Köpenhamn.Hittills har man på grundval av de många uppgifter från allmänheten som kommit in trott att meteoriden störtade i havet söder om Lolland-Falster.
Vägde flera ton
Till TV 4 Nyheterna Öresund säger Haack att fyndet väger ungefär 30 gram – att jämföra med de flera ton som meteoren tros ha vägt då den trädde in i atmosfären. Fyndet gjordes av en tysk meteoritjägare som i tre veckor intervjuat ögonvittnen och sedan ägnat en vecka åt att leta efter nedslagsplatsen. Delarna ska nu ställas ut på Geologisk museum. Det är första gången sedan 1951 som en meteorit hittats i Danmark.

Cosmos May Produce Meteors Starting March 12th 11MAR09
COSMOS IS FALLING:
The first fragments of shattered satellite Cosmos 2251 are about to reenter Earth's atmosphere. According to US Strategic Command, fragment 1993-036PX will reenter on March 12th, followed by 1993-036KW on March 28th and 1993-036MC on March 30th. These are probably centimeter-sized pieces that will disintegrate in the atmosphere, posing no threat to people on the ground.

-translation by Babelfish
An identified flying object illuminated for some seconds in the night Saturday in the DF and Goiás. Scientists investigate the phenomenon and they do not discard that a meteorite has entered in the atmosphere.
Scientists try to unmask the mystery around the torch of light in green tone that cut the sky of the capital of the country in the Saturday night. Inhabitants of the Federal District described a flying object not identified (Ovni) with a different brightness and behavior of an airplane.
Astronomers believe to be a meteorite or dissolute piece of the Lulin comet. Equipment of the University of Brasilia (UnB) had not yet registered a north-eastern explained signal of Goiás, where inhabitants also say to have witnessed a phenomenon similar to the testified one for the brasilienses.

Exploring the Pingualuit Impact Crater
by Charles O’Dale, Ottawa Centre (codale0806@rogers.com)
Introduction
The Pingualuit Impact Crater, located in northern Quebec at N 61° 16´ W 73° 40´, was the first structure in Canada for which an impact origin was proposed. The structure is classified as a simple crater, 2.8 km in diameter and 400 m deep. It is slightly larger than the smallest crater on the Moon that is observable from our planet (Meen 1951). The inner slopeof the 3.4-km-diameter rim averages 30° and the outer slope averages 10°. The rim extends to a diameter of ~4.6 km and continues gradually outward to merge with the surrounding terrain at ~6.6 km. The peak of the rim is ~160 m above the inner lake level and 120 - 150 m above the regional terrain. The lake within the crater, with a depth of over 250 m, is one ofthe deepest in North America. It is also one of the clearest in the world with a transparency of over 35 m. Dating using the isotope ratio 40Ar-39Ar (Grieve 2006) gives the impact structurean age of 1.4 ± 0.1 Ma. The Pingualuit Impact Crater was formerly named New Quebec Crater and, previous to that, Chubb Crater.

West, TX Meteorite hunter donates rare find 6MAR09
Meteorite hunter donates rare find
10:47 AM PST on Friday, March 6, 2009
By KGW Staff
PORTLAND -- A meteorite hunter from Portland is donating part of a recent find to Portland State University.
Video: Fireball during Texas marathon
Meteor fireball in sky
Meteorite donated to PSU
You may have seen the video of the fireball captured during a marathon last month near Austin, Texas.
When Patrick Thompson heard about it, he decided to spend eight days looking for parts of the meteor and he was successful. After searching on foot an average of 25 miles a day, he ended up finding 14 fragments of the meteorite.
For Thompson, it’s a true treasure.
“There's something about it, something about putting your hands on a rock and being the first person to touch it,” he said. “It came from space. These things are floating around up there, every time you see a shooting star, you're kind of reminded of the fact that these things are coming to earth, bombarding us all the time.”
Scientists said because Thompson’s latest meteorite finds are so fresh, the rocks are especially valuable.
Thompson said he plans to sell some of the rocks after donating at least one of them to PSU.

Student`s Science Fair Project on Earth Microbes 6MAR09
Students show off science projects
by Garrett Andrews
Herald Staff Writer
Article Last Updated; Friday, March 06, 2009
Speaking only slightly louder than the buzz of several hundred other student-scientists inside the reverberating concrete walls of the La Plata County Fairgrounds, Pagosa Springs eighth-grader Kendra Schlom explained her answer to the determining question of human existence: How did life on Earth originate?
She was discussing her entry in the San Juan Basin Regional Science Fair, a project that supports the idea that a meteorite could have transported early microbes to Earth.
In her project, titled "Finding the Origin," Kendra located the highest survivable temperatures for several primitive microbes and tested to see if these microbes could survive the temperatures a meteorite sustains when entering the Earth's atmosphere and crashing into the surface. She used basalt tiles to simulate chondrite meteorites.
Kendra and her father, a mechanic at Wolf Creek Ski Area, took an acetylene torch to samples of varying thicknesses, to analyze the time it takes the heat to completely penetrate the samples.
"From this information, I think that microbes could survive, because the temperature never exceeded the limit of what they could survive in," she said. "I believe that even if we went into lower thicknesses, they could survive, as long as the meteor is a quarter inch or thicker."
If she's right, then it's theoretically possible that these lone microbes ignited the evolutionary process that produced all of life as we know it.
Kendra, who hopes to study quantum physics at the Massachusetts Institute of Technology after high school, was one of 209 entries in this year's fair. About 20 winners will travel to the state science fair in Denver later this month.
Fair coordinator Jeff Hatfield said that as scores in science, technology and math continue to slide, events like science fairs become more important.
"CSAP scores and other assessment data show that we really need to ramp this up a bit. The fair is when you can actually get kids to dedicate their time to an actual science project. They're doing all the learning on their own.
"The bottom line is that we want these kids to be strongly rooted in science and technology," he said.
Not all the other projects had such divine implications as Kendra's, but most reflected hours of original study.
Bayfield eighth-grader Denvir Clarke placed bacteria in petri dishes and studied over time the effects of various germ-killing household cleaning products.
"I found that my hypothesis was wrong," she said near the end of a run-through of her presentation.
"Antibacterial soap is less effective at killing bacteria than regular soap."
Standing near a prototype of his invention was Kolton Miller, an eighth-grader at Mancos Middle School.

Speaking only slightly louder than the buzz of several hundred other student-scientists inside the reverberating concrete walls of the La Plata County Fairgrounds, Pagosa Springs eighth-grader Kendra Schlom explained her answer to the determining question of human existence: How did life on Earth originate?
She was discussing her entry in the San Juan Basin Regional Science Fair, a project that supports the idea that a meteorite could have transported early microbes to Earth.
In her project, titled "Finding the Origin," Kendra located the highest survivable temperatures for several primitive microbes and tested to see if these microbes could survive the temperatures a meteorite sustains when entering the Earth's atmosphere and crashing into the surface. She used basalt tiles to simulate chondrite meteorites.
Kendra and her father, a mechanic at Wolf Creek Ski Area, took an acetylene torch to samples of varying thicknesses, to analyze the time it takes the heat to completely penetrate the samples.
"From this information, I think that microbes could survive, because the temperature never exceeded the limit of what they could survive in," she said. "I believe that even if we went into lower thicknesses, they could survive, as long as the meteor is a quarter inch or thicker."
If she's right, then it's theoretically possible that these lone microbes ignited the evolutionary process that produced all of life as we know it.
Kendra, who hopes to study quantum physics at the Massachusetts Institute of Technology after high school, was one of 209 entries in this year's fair. About 20 winners will travel to the state science fair in Denver later this month.
Fair coordinator Jeff Hatfield said that as scores in science, technology and math continue to slide, events like science fairs become more important.
"CSAP scores and other assessment data show that we really need to ramp this up a bit. The fair is when you can actually get kids to dedicate their time to an actual science project. They're doing all the learning on their own.
"The bottom line is that we want these kids to be strongly rooted in science and technology," he said.
Not all the other projects had such divine implications as Kendra's, but most reflected hours of original study.
Bayfield eighth-grader Denvir Clarke placed bacteria in petri dishes and studied over time the effects of various germ-killing household cleaning products.
"I found that my hypothesis was wrong," she said near the end of a run-through of her presentation.
"Antibacterial soap is less effective at killing bacteria than regular soap."
Standing near a prototype of his invention was Kolton Miller, an eighth-grader at Mancos Middle School. He rushed through the features of the Bear-icade self-opening bear-proof trash can with the panache of a salesman, eagerly maintaining eye contact and gesturing with his hands, even as he went on bear-related tangents.
