                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Clouds and rain kept us closed all first half.  The cloud camera was
 opened and closed twice for rain, then opened a third time just
 before morning twilight.  Once the 2.5m ran EndNight, the sky
 improved and we opened the telescope long enough to get spectra on a
 few objects before more clouds moved in.  Seeing was good, and the
 telescope and CorMASS behaved fairly well.

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