Meteor

Description: The fireball was almost certainly a small asteroid disintegrating in Earth\'s atmosphere. A space rock measuring a few to ten meters wide moving at typical local-asteroid velocities would account for the fireball\'s speed and brightness. Reentry of manmade space junk has now been ruled out. Fragments of the impactor may have reached the ground; if so, they remain undiscovered and/or unreported. A brilliant green fireball startled onlookers across western Canada on Nov. 20th (5:30 pm MST) when it split the evening sky and fragmented during a series of thunderous explosions. \"The sky was lit up almost like daytime for 3 or 4 seconds,\" reports Gordon Blomgren of Alberta. Murray McDonnell of northwestern Saskatchewan says \"my wife and I saw a brilliant flash of blue white light, like lightning. About one minute later a long rumbling sound shook the house.\" Andy Bartlett video-recorded the event from a 10th-floor apartment in Edmonton, Alberta: \"The brilliant fireball appeared to be closer than the airplane in the upper right corner of this video,\" says Bartlett. \"I made the movie using a Canon A510.\"
