                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Dembicky
 Mostly cloudy skies with the threat of rain around 17:30 kept us closed
until after sunset.  Then the clouds seemed to part ways (well, we still
had a lot of thin cirrus).
We opened around 20:40 with marginal skies at best. Lots of cirrus and a
few clouds but since the observers were observing bright objects and it
looked like the threat of rain was past I decided to open and let them
have a go at it.
Clouds got in the way for about 45 mins during the first half.  The
observers stopped collecting data, but I left the enclosure open.
 2nd Half Observing Specialist: J. Barentine
 Switched over promptly at halftime under clearing skies.  The second half
progressed very well without incident under generally subarcsecond seeing
conditions.  Clouds moved in from the west around 04:30 but were thin
enough to observe through.
 Doug Duncan, 2nd half observer, asked to have a mention made in the log
that he was having trouble getting autoftp to work with his images.

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