Two very nice nights; these were all one-power from a poor location (Univ.
of Texas at Austin campus, 30.286 north, 97.739 west, 150 m). All the
magnitudes are estimates based on Quicksat predictions and sky objects.
I still feel pretty unconfident about magnitudes unless there's an easy
comparison object nearby, but I believe that Quicksat's predicted ones
are pretty reliable.

Also saw a nice GRO pass Monday morning; missed Tuesday morning Iridium
flare due to serious need to be asleep at that time! Haven't heard if
anyone saw it.
Question: Are *all* observations wanted in some such format as above, or
just selected ones that may be unusual in some way?
