                  ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The dome was opened for cooling at 19:00 under moderately thick
 cirrus.  The observer was able to get some twilight flats, and we did
 manage to focus once it was dark enough, but no science was possible
 so I closed the dome.  I re-opened for a clear patch at 22:50 and the
 observer got real data for a while under conditions of very good
 seeing (0.8" on the guider), before clouds returned again.
 After the program change, the clouds remained too thick to allow IR
 observing for a while, but I opened at 03:30 when it began to look
 possible.  The seeing was also very good on GRIM (undersampled at
 f/5).

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