Fireball streaks across Canadian Prairie, Crashes
November 24, 2008
The Canadian Prairie is still buzzing about a giant fireball that roared across the sky last night and slammed into the earth with a bright flash.

Scandinavian Fireball Sightings
January 17, 2009
On January 17, 2009, at 1909 UT, a meteoroid of unknown size hit Earth's atmosphere over Scandinavia and exploded with a thunderous, rumbling boom. The fireball was so bright it turned the nighttime sky blue.
More on the California Fireball - January 18
January 20, 2009
The fireball occurred on Sunday evening, January 18, at -5:30 pm (give or take 20 minutes). Amazingly this was only - 15 minutes after sunset for people on the coast so the sky was still very bright. The fireball must have been quite a spectacle to be seen against such a bright sky. Based on the reports submitted so far, it was seen from 4 states (California, Nevada, Utah and Arizona). Here's a map of the sightings reported so far. Most people said it was a white/blue though a few observers noted it changed into many colors. This is consistent with a meteor. The fireball ended its passage through the atmosphere with a bang, something astronomers call a "terminal burst". This marks the final break-up, or explosion, of the small asteroid that created the fireball. Many reports also mentioned that a smoky trail was visible for several minutes after.
Another California Fireball
January 19, 2009
I have received a few reports about a bright fireball seen across California. Sightings have been sent in from San Francisco to San Diego. There is some disagreement on the time with some people saying it occurred on January 18 around 5:40 pm PST and others saying it happened on January 19 around 4 am PST. So perhaps we are talking about 2 unrelated but spectacular fireballs, the evening one was seen over southern California while the morning one was a northern CA object.
Fireball in Arizona Sky
January 18, 2009 10:47 pm
I'm in Phoenix and at about 6:15 pm I was taking the family out for dinner when I saw a fireball in the sky WNW of here. It was the biggest fireball I have ever personally seen. Did anyone else see it? [and from another] I saw it looking east at about 75 degrees at 6:08 pm with a yellow-orangish tail, bigger than a shooting star lasting a second or two from Highway 4 traveling towards Murphys, CA (central Sierra Foothills)
Bright Light in Southern Skies Thought to be Satellite
January 19, 2009
Queries about a bright light in the southern skies last night have been coming into the Mount St John Observatory. A nzherald.co.nz reader, Shannon, also saw the light and said: "I'm not 100% sure what it was, but it looked like a comet or something entering through the atmosphere last night around 10.30 pm to 11 pm. "It was a bright white light and was moving extremely fast to be a plane, and looked to be breaking up as it moved along, as its colour changed to orange." Alan Gilmore, a resident superintendent at the Mount St John observatory, said reports from Christchurch described the bright object in the sky shortly after 10 pm that was visible for between two to three minutes and left a glowing trail behind it. "My best guess was that it was a re-entering satellite. A comet does not move like that, it stays more or less fixed against the background stars unless it is very close to the earth, you need to watch it for two or three hours in order to see it moving," Mr Gilmore said. He said it moved too slowly to be a meteor, which would be gone in two seconds. "But everything fits with a re-entering satellite, that is a satellite that is heating up because of the friction of the air, probably 100km or higher up in the air, it's glowing white because it's heating up and it's leaving a trail of charged, excited atmosphere gas which glows," said Mr Gilmore. He said the trail could have also have been smoke picked up by the sun at such a high altitude. "That's my best guess," he said.

Observers in Massachusetts and Rhode Island are reporting a "huge, pulsating blue-green fireball" sighted within minutes of 8:48 pm EST on January 23rd. It was bright enough to be seen through heavy cloud cover, according to one witness.
