     Sorry for the lack of a reply. I suspect you saw it. The satellit =

     There were two payloads...FAISAT was attached to the top of a=20

I have a really early observation of two objects related to the Faisat =

however, I don't know which they are and whether Faisat and rocket body=

seperated by about 3s. The first one was brighter than the second one, =

flashing with roughly a 5s period, maxima at roughly 1m5 (brighter than=

Using elsets, I identified the "first one" as 97 52C, and "the second o=

I reported this to Eric Rosenberg but never got any reply. BTW, was thi=
