                  ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 The first observer noted during cals that the high frequency pattern noise
 in the spicam biases had returned. Image copied to the image archive directory
 /export/images/keep/spicam/20041020
 Cloudy skies prevented us from opening until 00:30. The first half observer
 threw in the towel for the night. Then by the time I did the instrument change,
 focused and checked pointing it was the beginning of the second half. The
 second observer did not really gain any extra time. At 0318 I lost
 communications with the guider. running down the troubleshooting checklist
 I determined that it was a hub problem and restarting the gcam process solved
 the error.

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