"Just observed an ORBCOMM at 12:10 UT 27 Dec 97.  I used
an 8" telescope just in case, although it would have been
easy to see in 7x50 binoculars at magnitude 6-6.5."

I suspect that it was a matter of phase angle. This obs was in the north
after sunset. Perhaps not as good as the obs in December.  Or my estimate
was really off (not likely off by two magnitudes though).

Still interesting to see 8 objects that closely spaced. I think there may
be a launch of 12 objects soon (perhaps Globalstar)...Unless I am thinking
of the recent Zenit failure.
