To amplify Marco's remarks. Here is the result of a query on OIG I just did
to find decay oct 16 to Oct 18.

The Soyuz TM5A rocket decayed around 0850 UT October 16, south of
Tasmania, so seems unlikely to have lasted nearly 18 hours later.
1987-79BG is on the face of a possiblity, as this is an object in an
eccentric orbit. The final 5 TLEs show inconsistencies among the
drag, and eccentricity.

However the orbit plane transit over Sirko Molau's location
is around 9 or 17 hours UT, which means it cant be that however confused
about #28212 the SSC is!
I think it was a slow meteor, and have said so to Sirko, and
the meteorobs list.
Not having seen the Northern Sky much even when I was there 6 years ago,
I find it difficult to identify the stars patterns in the movie. Its a really wide,
like 50 degree FOV. Can somebody tell me what direction the object was moving?
