Orion 3 bright flashes

Last evening ( 1999 10 12/23:43 UTC ) while looking for 25727 (99-024A,
Orion 3) in binoculars, we were startled when it displayed a VERY
brilliant brief flash. It was essentially invisible before and after
the flash (local light pollution and a somewhat hazy sky), but about
20 seconds later it flashed again - easily visible to the unaided eye -
brighter than the first magnitude (i.e. comparable to Altair's 0.76).

We'd seen this object twice before (1999 06 19/02:15 UTC at apparent
magnitude 5-1/2 and 1999 06 20/02:02 UTC when it flashed to about 3rd
magnitude) but never this bright. Has anyone seen this interesting
object recently? (There were several postings a to SeeSat-L a few
months ago regarding 99-024B, the rocket, but I don't recall any
details about the Orion 3 itself.)

We'll try to observe it more carefully (including timing the flashes)
next time.
