Bolide of N. California

Oct. 30th. 2009 0316 Hrs. PDT.

Final Report:
Locaton North Central California. (Yuba City.)
Detonation Brightness = >Full Moon.
Duration = 2 Seconds.
Starting Elevation = 60 degrees
Starting Azimuth = 79 deg. True North.
Ending Elevation = 43 degrees.
Ending Azimuth = 72 deg. True North.

-2 small post explosion ablating products found running movie at 1/4 speed.
A short but very nice image and Q-Time movie. Data will be sent to AMS.
YCSentinel

Initial Reports:

Event was 2 seconds long.

Starting Elevation and Azimuth is 60 degrees Elev., 79 degrees Azimuth True North.

Ending Elevation and Azimuth is 43 degrees Elev., 72 degrees Azimuth True North.

1/4 speed movie indicates a post explosion of 2 small ablating products.

Peak brightness exceeds full moon.

Exceptionally clean explosion with (no initial evidence) of post explosion
wake light or ablation products. High elevation event. I have not yet
measured Azimuth & Elevation but will do so later today and post it here.

Without further examination at this time, the apparent peak light period too
brief to even saturate a single frame but could easily be as bright or
brighter than the Sun. Over 75,000 pixels peak in Sentinels light graph.
Graph looks like a needle point. Super clean!

Pacific Ocean Meteor 28SEP09 Update- 2OCT09

Images by YC Sentinel (c) 2009
Pacific Ocean "Bright as the Sun Meteor" -- Update
first reported by YC Sentinel on 28SEP09.

Calculations have been made by YCS on the estimated detonation over the Pacific Ocean of the small asteroid recorded on video on Sept. 28.

Video of the event: http://www.geocities.com/stange34@sbcglobal.net/v20090928_0226.mov
(let the video loop several times to see the whole flash)

Yuba City Sentinel--
"This event was at 0226:56 PDT in the Morning hours of Sept. 28th, 2009.

Fireball origin was about 6 degrees above horizon, and descended to about 2
degrees above my horizon. (Roughly estimated).

Initial azimuth was 311 degrees. Detonation occured at 314 degrees.
Follow-up burn out took 0.6 seconds and appeared to go to my horizon limits.

Peak light intensity exceeded Sandia Sentinels 30,000 pixel scaling limit."

"Using the rough elevation & azimuth data(West & 45 deg.) of the Oregon
observers Sept. 28th posting on AMS, and my accurate azimuth only,
disregarding my visual horizon estimate....it appears that the detonation
point is ~250 miles off
of the coast of lower Oregon and ~425 miles from Yuba City on a bearing of
314 degrees True North.

I believe the Oregon observer is likely near Medford(from my past memory),
and I have done a rough pictorial triangulation.

Given the great distance and the brightness from the two observation
points....Is it likely that this event is not a meteor, but rather a
small asteroid which detonated?

"Tungustita" of sorts....????

Bolide News- Fireball as "Bright as the Sun" Seen 29SEP09

"Pacific" Fireball as "Bright as the Sun" Seen
Distant event on horizon occured at 0226 hrs., the morning of Sept. 28,
2009.

Will marshal the Sentinel facts & measures and post composite with movie.
Could be over the Pacific Ocean off the North Coast of California at the
maximum range of this station.
(No evidence that this Bolide had spin or rotation too....)

Update pending.

North in Yuba City, California.AMS eyewitness report time is: May 25th, 2210 hrs. PDT 28MAY09

Fireball or ISS? 25MAY09
25MAY09 Fireball?/ISS? Report Updated 28MAY09

Anyone else get a photo of it, or see it around Glen Ellen, California? Glen Ellen is near the center of Santa Rosa-Napa-Petaluma triangle. I am North in Yuba City, California.
AMS eyewitness report time is: May 25th, 2210 hrs. PDT, traveling from NW30 to SE90 YCSentinel has a capture of a very bright object travelling slowly apparently toward my zenith FROM the North-West.
Sentinel camera timed out at 12 seconds with the object still bright and moving. I thought it might be a slow airplane.....until now!
My time is May 25th, 2211:34 Sentinel Light Curve is huge lasting 370 frames before time-out. I have a short (12 second composite picture & a movie) of what I did capture with the Sentinel system.

My 2nd "Handyavi" system has a corrupt file which occured just before this event. (0506 UT time). That corruption may have been caused by this long lasting fireball.
I am unable to recover that file unfortunately.

Received from Marc Fries PhD. c/c to Peter Jenniskens-- YCSentinel 28MAY09
"I haven't retrieved the radar data for this one yet, but I strongly suspect we're looking at an ISS pass.
The following pass is recorded for Sacramento using the Heavens-Above website:
25 May -2.5 22:09:04 10 NW 22:11:59 87 NE 22:12:02 85 E This records a near-zenith pass starting around 2210 and starting out of the NW. Cheers, MDF"

New North Central California Fireball Event May 27 at 0228:46 PDT 27MAY09

JUST RELEASED! will soon be updated!!!! check back
May 27 at 0228:46 PDT
This Fireball appears mid-sky south of North Central California.Characterized by what appears may be the ejection of objects which begin a now visible brief ablation or heating after a short distance from the core on either side.I can only speculate* (*no credentials for this) that PART of this fireball fragmented explosively and it may be that cool fragments reached ablation velocity momentarily. They appear stationary in my images after heating. A possible meteoroid dropping event?

Soon to be updated by YCSentinel

New Fireball event May 27 at 0228:46 PDT

New event May 27 at 0228:46 PDT image by YCSentinel

Composite image scaled with a detail insert. The movie clearly shows the ejected(?) particles.
Date and time is in the file name: May 27 at 0228:46 PDT

Date-Time 20090527_0228:46 PDT. (0928:46 UT)

Duration = 3 seconds.

Start Azimuth = 186 Deg. true North.

Start Elevation = 58 Deg.End Azimuth 153 Deg.

End Elevation 47 Degrees

Looks like the 90 second event was an ISS satellite pass.

I am hoping I can bring out the positions of the apparent fragments in the composite. If not I will attempt inserts at the top of the composite image showing where they were in respect to the core at their separate visible times.

The movie shows these hot fragments very clear during the event.
