              ------------- ACTIVITY LOG --------------
 Observing Specialist:  R.McMillan
 We observed through clouds for the first few hours of the night, but
 when they got thicker and radar showed nearby returns, I closed.
 After midnight the sky cleared abruptly, so we were able to observe
 for the remainder of the night.  There was one hang-up of the DIS
 slitviewer, likely due to colliding commands.  Otherwise, the
 telescope and instruments behaved nicely.
