                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Dembicky
 Frustrating 1st half of the night with passing clouds.  We also got a
 couple of errors (usually after stopping DIS) about the shutter being
 stuck open.  This happened once last night, tonight it seems more
 frequent.  A 'dis shutter close' fixed the problem.
 Humidity closed us at 23:15.
 The secondary temp was reading high all night (not as bad as last night
 but it was the highest temp reading but still on the order of +2C off
 from the others).
 2nd Half Observing Specialist: R.McMillan
 We re-opened after midnight when the humidity spike seemed to be
 past.  Seeing was poor, but skies were nicely clear for the
 remainder of the night.

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