What if you're driving down the street and an object from space shoots across the sky right in front of you? Such was the case last week for many people in south central Canada. Specifically, an extremely bright fireball, presumably a desk-sized meteor from deep space, flashed across the sky just after sunset on 2008 November 20. The bright fireball was recorded on many images and movies, including the spectacular video shown above that was captured by a dashboard camera of a police cruiser in Edmonton, Alberta, Canada. Because at least two streaks appear to be visible, the falling object likely broke up into pieces as it fell deep into Earth's atmosphere. By triangulating fireball images from several simultaneously recorded sources, astronomers hope to find an approximate orbit from whence the object came, as well as the likely place(s) on Earth where large pieces would have impacted, were they to have survived entry.

Canadian researchers reported Friday they had found some debris from a 10-ton meteorite in Saskatchewan that lit up western skies last week.

In a statement, University of Calgary planetary scientist Dr. Alan Hildebrand and graduate student Ellen Milley said they had "located several fragments of meteorite Thursday afternoon and are conducting a search of the area to collect some of the estimated thousands of meteorite fragments densely strewn over an estimated (13-square mile) area near the Battle River."

The find was made near Lloydminister, Saskatchewan, which is on the Alberta-Saskatchewan border

Note that the many elliptical lakes are a product of the last continental glaciation over 10,000 years ago and are not due to meteor fragments. In any case the imagery dates from August 23, 2002 and so is much older that the meteorite strike.

CALGARY, Alberta, Nov. 26 (UPI) -- The asteroid that lit up western Canadian skies and startled thousands of people last week weighed about 10 tons, a University of Calgary researcher said.

In a news release, Alan Hildebrand, coordinator of the university's Canadian Fireball Reporting Center, said the asteroid that was seen in Alberta and Saskatchewan last Thursday was likely about the size of an office desk, CTV News reported.

Hildebrand said after analyzing scores of amateur videos and pictures, he determined the asteroid was traveling at a relatively slow 33,000 mph when it streaked across the early evening sky. The report said most rocks entering Earth's atmosphere travel 30 percent faster than that and burn up entirely before they reach the ground.

Hildebrand said he has mapped out a region in western Saskatchewan where he believes fragments could be found, based on witness accounts and video evidence.

"Many witnesses reported seeing a cluster of red fragments continuing downward in the sky after the fireball exploded," he said. "These represent the rocks slowing down that will eventually fall to the ground as meteorites."

He said public response to the event was "the largest that we have ever had in Canada," the report said.

wow, i need one piece!...(:
thanks Hill took care again!
nice amount of information just as we have never thought another way from you!
best,

Some pictures are now available.

Note: The location has been refined and the placemark folder in my previous post has been edited to show the change.

More has been discovered about the Buzzard Coulee meteorite swarm. Here's a link to a site with more photos and a link to a new piece of video of the original meteor's flight.

The largest meteorite fragment to be recovered in the first days was this 13 kg whopper which creating a form fitting indentation 5-10 cm deep before bouncing out and resting on the frozen ground a few cm away.

The original folder has been edited to show the location where the largest (13 kg) fragment was found.

Here is the latest update from the University of Calgary:

A University of Calgary-organized team recovered more than one hundred meteorites from the November 20 meteorite fall southwest of Lloydminster, Saskatchewan/Alberta, which is expected to set a new Canadian record for the largest recorded meteorite fall.


�Finding all we could before the snow came on December 6 was a real challenge and tough on searchers with wind chills routinely colder than �20 degrees,� said Dr. Alan Hildebrand, holder of the Canada Research Chair in Planetary Science. �We did as well as we did by collaborating with experienced researchers from The University of Western Ontario including Dr. Phil McCausland and Dr. Peter Brown.� Both Hildebrand and Brown are veterans of the Tagish Lake (2000) and St-Robert (1994) meteorite recovery efforts and McCausland is a veteran of the Tagish Lake recovery.


Volunteer searchers numbered up to twenty people per day including local residents, U of C staff and graduate & undergraduate students, professors from the University of Saskatchewan and the University of Regina, amateur astronomers from the Saskatoon, Calgary and Edmonton Centres of the Royal Astronomical Society of Canada, and geoscientists from ConocoPhillips Canada. Most searchers found at least one meteorite despite having a thin layer of snow down the last five days.


�The last day that the search teams were out, it snowed all day and we still found five meteorites which is ridiculous. It shows just how many are out there,� Hildebrand said.
Using the abundance of meteorites on the pond where U of C grad student Ellen Milley found the first fragments on November 27, Hildebrand calculated that about 2,000 meteorites of more than 10 grams in size occur per square kilometer in the northern part of the strewn field, and probably more than 10,000 meteorites of this size are on the ground altogether. Many local residents and landowners also found meteorites, as well as persons from across the prairies and meteorite dealers who traveled to Saskatchewan to try their luck.


�We have had great cooperation from landowners, who are having a once-in-a-lifetime experience of a meteorite harvest,� Hildebrand said. �Approximately 130 well-substantiated meteorites have been found totaling about 40 kg, but probably double that number, weighing more than 50 kg, have been recovered.�
Hildebrand encourages everyone who has collected specimens to please send him the masses (in grams) and locations (GPS coordinates, NAD27 datum) of their finds to help map the strewn field.
Milley and Hildebrand have formally proposed the name Buzzard Coulee to describe the fall to the International Meteoritical Society. The name comes from the picturesque valley near the hamlet of Lone Rock, Sask. where the first meteorites were discovered.
