                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Russet McMillan
(Russet forgot to e-mail me her 1st half log, but we were basically closed
all night due to snow and she ran the snow program.)
 Observing Specialist, 2nd Shift: Jack Dembicky
Snow, snow, and more snow.  About 7-10 inches on the ground so far and
still falling!  Snow program was run all night.  02:19 Power dropped out
for about 5 sec sitewide and tripped the dome enclosure controller power.
I restarted the snow program after resetting the controller. We had a more
severe power outage at 03:50 and the generators started this time.  I
spent the remainder of the night plowing snow.  We were back on the mains
sometime before 8:20 and everything seemed happy. About 10 inches of snow
total accumulation.
