The long duration and general flight direction (SSW --> NNE) suggested large space junk reentry. And indeed, the beautiful radar signature that lasts for over a half hour looks just like that of past satellite reentries. (Marc Fries was on the ball and found the unmistakable signature yesterday.) Trouble is, I can't find a good candidate in the USSPACECOM catalog that could have been responsible. Some have suggested Cosmos 2495 (which ~was~ making a northbound pass over Colorado at about that time), but I don't think that could have been it. That satellite's altitude should have been around 230 km at the time -- low, but certainly not in danger of immediate reentry. The only way it could have reentered is if it had a catastrophic breakup sometime after 17:00 UT on September 2nd (the epoch of the most recent orbital elements for Cosmos 2495). I put together a kmz file with 19 separate radar sweeps from the Denver and Cheyenne Doppler radars between 05:06:56 and 05:34:15 UT on 3 September (11:06:56 pm to 11:34:15 pm Mountain Daylight Time). By playing with the Google Earth slide bar, you can see the long debris cloud drifting eastward with the prevailing winds. If anyone would like a copy, just let me know. Perhaps there is some satellite debris waiting to be found somewhere along the ~100-mile-long line from Keenesburg, CO up to Albin, WY. --Rob -----Original Message----- From: Meteorite-list [mailto:meteorite-list-bounces at meteoritecentral.com] On Behalf Of Shawn Alan via Meteorite-list Sent: Thursday, September 04, 2014 1:47 PM To: Meteorite Central Subject: Re: [meteorite-list] CO WY Meteor Approx. 2230 MDT 02SEP2014 long duration/fragmentation Hello Listers If its a fall, its perfect timing with the gem show in full swing in Denver.
