                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The night started with clouds, high winds, and dust, and progressed
 to humidity, high winds, and snow.  We got about two inches of snow
 at the site.  I ran the snow program for most of the night, but left
 the roof heaters off since temperatures were well below freezing.
 Around 07:32 UT, there was a power outage which lasted about 10s.
 Afterward, indicator lights showed that utility power had come back
 on, but the generator was running anyway.  The enclosure needed to
 be reset, but everything else seemed fine.  I re-started the snow
 program.
 In the morning, I left the telescope pointing south.
