                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Clouds rolled in around 00:00.  We had a sucker hole around 02:15, I
 mounted DIS and started taking the Bias, Flats, and wavecals, as the
 sucker hole evaporated (it didn't look like it was going to last long),
 just to be ready if it did clear later.  It was again cloudy by the time
 I finished the biases, flats, and wavecals.  Clouds never parted long
 enough to open and get useful data, during the 2nd half.

     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
