                  ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Clouds of varying thickness came and went all night.  Because the
 weather satellites stop working in the middle of the night this
 close to the equinox, and the radar stations could only see
 reflections off the inversion layer, I was somewhat conservative
 about closing when the clouds got moderately thick, even though the
 observers estimated they could shoot through.  Aside from the
 weather challenges, there was one crash of the NA2 guider
 controller, which took several minutes to reset but didn't cost any
 observing time.  Everything else worked perfectly.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
