Dirk and list,

this very, very probably was a decaying rocket stage, as our knowledgeable list member Dr Marco Langbroek wrote:

"...Place, track and time closely coincide with the predicted re-entry of a stage of the Soyuz rocket (06-063B, #29679) used to launch the French COROT space telescope on December 27th from Baikonur. The sighting is only a few minutes later than the nominal predicted decay time, and at the correct geographic location and direction of movement from the last know orbit for this object..."

I have been into optical satellite tracking for many years in the past, and by virtue of such close coincidences of observed facts with a reliable decay prediction from NORAD (...usually issued shortly before the decay actually happens) you can assume almost beyond any reasonable doubt that this indeed was a satellite decay, a Russian booster burning up at a heigt of may be 60-70 mi, and a speed of almost 5 mi/sec. Meteorites are moving pretty much faster!

May be another expert on may cast some light on this - Rob Matson! Rob, are you out there?

I would have been very happy to see this in person!
