Observed what must be the Zenit, at about +2 when it first appeared.
There were three or possibly four one-power maxima in about 20-40 
seconds, each one significantly fainter than the previous, due to 
deteriorating phase angle and increasing range.  It was one-power
invisible between the maxima.  Here's the Quicksat output:

  30.286  97.739  550.   CBA, UT, Austin, Texas   2000  7.0 12 F F T T T
