Opportunity Continues Meteorite Examination - Sol 1981-1987

Zoe Battersby was out for an early walk along Jimmy Amers beach in Kaikoura at around 6.10am when she noticed a "very large meteor".
"It was very bright - the size of a streetlight. It looked like it fell into the sea," she said.
Alan Gilmore, resident superintendent of the University of Canterbury Mt John Observatory said meteors enter the atmosphere over New Zealand "several times a year" but he doubted that the rock made it to the ground or water level.
“This meteor is very typical, and often they burn up at about 70kms up. It’s very rare for them to actually land. They are coming into a thicker atmosphere, travelling at 30km a second. The friction is strong and they slow up and start to break up. It’s like throwing a stone at a concrete path,” he said.
Gilmore said as the meteor breaks up, witnesses often see a bright flash known as a 'terminal fireball'.
He said meteors "burning up coming through air - white hot with friction - start to glow". Meteors could be seen from as far as 100kms up and could be seen from almost 1000kms away.
"They are spectacular, often a bright white centre which is the actual rock, - a tiny, brilliant star - with a teardrop-shaped glow that’s brilliant emerald green caused by the oxygen and the radiation coming off the rock," he said.
Gilmore said on the rare occasion that a meteor lands - then becoming known as a meteorite - its arrival is often heralded with a sonic boom caused by the temperature layers that exist closer to the surface, below 60kms.
Because of the range of reported sightings, Gilmore expected the meteor entered the atmosphere somewhere over the North Island.
"The impression of closeness is deceptive. Because they are bright, people think [the meteorite] landed a couple of paddocks away."

AMSTERDAM – It's not green cheese, but it might as well be.
The Dutch national museum said Thursday that one of its prized possessions, a rock supposedly brought back from the moon by U.S. astronauts, is just a piece of petrified wood.

The Johnstown Breeze
JOHNSTOWN – A piece of the Johnstown Meteorite has again landed in Johnstown.
A small part of the rock from space that fell July 6, 1924, was presented to the Johnstown Historical Society Tuesday night by its owner, Misty McNally.
McNally, a former Johnstown resident who now lives in Kansas City, had the fragment of the meteorite sent to town via the postal service. She marked the package “fragile” and so ensured the meteorite’s second landing was softer than the first.
The 1924 landing startled folks from Johnstown to Mead, as pieces large and small rained upon the area that Sunday afternoon. Small fragments hit roofs like hail, but it was one large chunk that made history. It landed by the entrance of the local cemetery and interrupted the funeral of John Moore. Startled funeral go-ers grabbed the shovel intended to fill in Moore’s grave and ran to unearth the smoldering piece which smashed nearby.
The fact the fall was witnessed by so many and the pieces recovered immediately is a rarity even now. But it was considered as amazing then, and tiny Johnstown became famous overnight. The meteorite itself is a rare type, an igneous cement-looking rock which has fooled seekers for years.
Jack Murphy, an expert on meteorites who retired a few years ago after 35 years at the Denver Museum of Nature and Science, told the story of the meteorite Tuesday night. He also told several people who brought pieces of what they hoped were the meteorite they did not have a part of the celebrity rock.
One who did, however, told her meteorite story.
Sandy Wiest Lebsack showed her piece, nicknamed “Chip,” to the group and told how her grandfather, Peter Wiest, kept it for years and passed it to her. That has been the only local documented fragment in this area of the 28 confirmed pieces recovered, said Murphy. The largest piece was sold after its fall to the Denver museum and then to the American Museum in New York, where it is still. But now McNally's gift to the museum can be added to the list of documented fragments and a piece of local history has again come home.
Murphy had a gift for the museum too. He presented a copy of the front page of the Denver Post in July 1924 with the picture of a little girl and recovered pieces of the Johnstown meteorite. That little girl, “little Miss Beth Bailey,” as the article states, is Murphy’s mother. Her father worked at the museum, and she was there when the specimens were brought out to show the press. Therefore, she was added to the photo with the space rocks; rocks her son has spent years researching.
The piece of the meteorite and the front-page picture will be added to the display at the museum telling about Johnstown’s visitor from space.
Editor’s note: According to a story published about a year ago in The Johnstown Breeze, it was reported a 29th piece of the Johnstown Meteorite had been found by a Johnstown resident. After the story was published, the sample was examined by Murphy, who has said he does not believe it is a piece of the meteorite.
