I have asked if there was any expected spacejunk re-entry over on meteorobs
http://lists.meteorobs.org/mailman/listinfo/meteorobs or
http://groups.yahoo.com/group/meteorobs/ and was kindly and promptly answered by Tony Beresford, a world famous expert on such matters. There was nothing expected for that time - so was probably just a good old fashioned natural Fireball
!
