                  ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: B.Ketzeback
 The first half was clear with good seeing. The observer complained around 2100
 that they couldnt locate their fields. I checked pointing and the altitude
 magnasensors but found no real problems. We slewed to Altair and the pointing
 was verified and then a new field was recognizable by the observer. I am not
 counting any downtime for this because nothing seemed wrong. The first half
 also had moderate winds which showed visible windshake in the slitview images
 and with the guider.
 2nd half Observing Specialist: R.McMillan
 We observed for a little bit, we closed due to high wind, we
 observed a little bit more, we tried to dodge some clouds, we closed
 due to high humidity.

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