I made an image showing the position of the rocket stage at the moment of the 
sightings in a bit more detail than at the above URL. It is visible here:

Movement is from north to south along the red line. There is some (minor) 
uncertainty in the stage's position along it as the orbit of a decaying object 
changes quickly. At this moment it should be at a maximum atmospheric altitude 
of 130 km but likely already lower when in decay (Chris mentions 60 km).

The 8 km/s Chris mentions from his all-sky data is exactly the speed an object 
decaying from an orbit around the earth should have. Meteors on the other hand 
have a minimal speed of 11.2 km/s
