                  ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 The sun did not appear out from behind the clouds long enough today to
 melt the several inches of snow and ice on the dome. I had left the roof
 heaters on all day and tonight as well. It seemed to help some but not
 enough to keep us from opening. Several times tonight well after dark, I
 could hear over the intercom, large chuncks of ice and snow fall off the
 dome..
