More than a year ago, in July 2007, International Space Station astronauts 
threw an obsolete, refrigerator-sized ammonia reservoir overboard. Ever 
since, the 1400-lb piece of space junk has been circling Earth in a decaying 
orbit--and now it is about to reenter. If predictions are correct, the 
"Early Ammonia Servicer" (EAS for short) will turn into a brilliant fireball 
as it disintegrates in Earth's atmosphere during the early hours of Monday, 
Nov. 3rd. Uncertainties in the exact reentry time are so great (plus or 
minus 15 hours at the time of this alert) that it is impossible to pinpoint 
where the fireball will appear. At the moment, every continent except 
Antarctica has some favorable ground tracks.

Readers should check our Satellite Tracker (http://spaceweather.com/flybys/) 
for possible overflights. Before reentry, the EAS will seem about as bright 
as a 2nd or 3rd magnitude star, similar to the stars of the Big Dipper. 
During re-entry, the disintegrating reservoir could light up like a full 
Moon.  Flyby predictions should be regarded as approximate because the 
orbital elements of the EAS are now changing so rapidly. Updates will be 
posted on http://spaceweather.com.
