I was extremely lucky to see this as I left a customers place. Night sky lit up. I've seen low level meteorites before, but this was very bright. Meteorite Search for Meteorite |

Looks just like a sunset. |

Looks just like a sunset. Thats not the sun though. 5:30pm at this time of year here, its already dark. The flash of light it let off when it broke up was unreal. Latest info I've heard, they figure it may have been up to 12 meters diameter. |

Something that large should be located very quickly. It's understandable that at 53-1/2 degrees north the Sun would set very early at this time of the season. Down here 15 degrees farther south the Sun has just barely set at 5:30 PM. On the east coast (of the US) at this latitude it would be much darker, though. |

Looks just like a sunset. Closer to 12 centimeters probably. News story Despite its size and the noise it made entering the atmosphere, the meteor was probably no bigger than a grapefruit, Edmonton space educator Randy Atwood told CTV Calgary. The meteor may have broken into small pieces before hitting the ground, or it may have burned up entirely before touching down. |

I've read the size as possibly being between a chair and a desk, but I seriously doubt it was 12 meters in diameter (the size of a 3 story townhome?). |

I've read the size as possibly being between a chair and a desk, but I seriously doubt it was 12 meters in diameter (the size of a 3 story townhome?). That's what I thought too. I'll try and find the article. They must be talking about it's original size, before it broke up. Here it is. "The rock seems to have flown in the general direction east of Red Deer and west of Saskatoon and appears to be about 18 metres or larger, he added." |

A recent study said it weighed up to ten tons and was as big a large car. At 15000 feet it broke into a dozen or more pieces. If you could find the impact site a metal detector would also be helpful since most meteorites have a rich metal composition. when it broke up it showed on radar. |

That certainly seemed like a very large stone coming down. We had a large meteorite fly across the sky one night when I lived in Wisconsin In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

If a ten-ton meteor broke into a dozen (or even more) pieces the holes in the ground should be very evident. Those pieces would probably be falling at terminal velocity and being solid rock or iron would hit the ground at several hundred miles (kilometers) per hour. |

when I was in germany a potatoe sized rock fell in a farmers field it made a hole 7 feet deep and over 20 feet in circumference. It hit in mud and was recovered intact. These can come in at 60,000 mph and iron ones will hit the surface. |

The rock that formed meteor crater or barringer crater in arizona was maybe 550 tons. The size of a train engine. It threw material out to 60 miles and had effects out to 100 miles. |

Those pieces would probably be falling at terminal velocity and being solid rock or iron would hit the ground at several hundred miles (kilometers) per hour. the burning trail in thje atmosphere is airbraking the rock. most Meteors fall to earth at around 120 mph when they reach the ground. 120 mph being the average terminal velocity. larger objects that enter the atmosphere tend to not slow enough from the atmosphere and do create craters.

That potato was probably only part of the meteor that made that hole. I don't see how something that small made a crater that big unless it was traveling at several miles (kilometers) per second. With something that small the air would brake it to terminal velocity and it would go into the ground only a few centimeters. A slightly bigger rock (say one meter diameter) might still be going at terminal velocity but that terminal velocity would be somewhat more than that of a human falling broadside to his motion (about 120 mph or 190 kph) due to the weight, density, streamlining, etc. |
