                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Dembicky
 Excellent seeing again tonight, sub arc sec, under clear skies.  I opened
 the telescope around 19:45, when the observer had finished their cals.  I
 tweaked the focus as we observed, but it was fairly steady.
 2nd Half Observing Specialist: R.McMillan
 Second half had thin high clouds most of the time, with moderate to
 very good seeing.  Everything worked perfectly.

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