I checked with this picture taken by Ray Palmer :
http://spaceweather.com/swpod2007/20feb07/Palmer.jpg
and this track is definitely from #28944. On this picture I figure the
exposure was from about 17:10:30 to 17:16:00 UTC.

Here is a 3D view of the satellite orbit at 17:15 UTC on Feb. 19

Wow!

That is the upper stage that shut down prematurely, stranding the Arabsat 4A
(06006A / 28943) communications satellite in a 51.5 deg, 507 X 14701 km
orbit.
Must have retained a large fraction of its propellant load.
