                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: W.Ketzeback
 Around 16:00 this afternoon the site recieved about 1/2 inch of very
 wet snow. I ran the snow program to see if I could get some of it off
 the roof of the enclosure but when I inspected it visually right at
 sunset there was alot of ice on the railings and roof. I restarted the
 snow program and told the first half observers we would not be opening
 due to ice. The roof heaters have been on all afternoon. Shortly after
 20:15 the humidity spiked and I stopped the snow program as well.
 2nd Half Observing Specialist: R.McMillan
 Ice on the dome and continued high humidity for most of second half
 kept the telescope closed.
