                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Clouds, high winds, and dust kept us closed for most of the evening,
 then we were able to open for a hole with bad seeing before clouds
 closed in again and made observing impossible for a couple of hours.
 Then the edge of the system passed again in the other direction and
 we got some more observing done, this time with good seeing.
 The echelle slitviewer needed to be rebooted twice -- once (software
 reboot) at the very beginning of the night and once (power cycle by
 means of unplugging) during observing, which cost a few minutes.
 The echelle slitviewer filter wheel was also more recalcitrant than
 usual and got reported, although it didn't cost any time.

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