Title: Reentry Observed Over LaGuardia (LGA)?
Post by: sdsds on 01/30/2011 02:26 AM
During descent into LaGuardia Airport this evening a passenger aboard a commercial flight (SWA 3130) observed a "fireball" streaking across the sky.  The aircraft was still above the clouds at the time, but had begun descent.  (The flight is reported to have landed at 8:43 PM EST on 29 Jan 11.)

Could this have been e.g. the reentry of the upper stage from the recent HII-B launch?

Could have been one of thousands of items or a meteorite - what would lead you to think it was from HII-B?

The H-IIB flight 2 payload was separated into a 200x300km orbit.  The second stage engine re-ignited after payload separation (Jan 22) in a "controlled re-entry test".

But no, I cannot find evidence that this evening (Jan 29) was the expected time of re-entry.

The upper stage used to orbit Progress a few days ago offers another possibility.

I found a predicted reentry for 31 Jan:  a Long March 3A stage from the Dec 17,  2010 launch.

Nice that The Aerospace Corporation is keeping track!  But with nothing on their calendar for today, the natural object theory (i.e. meteor) is gaining traction....
