                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Clouds, humidity (our outside temperature sensor seemed to be in
 disagreement and fluctuating compared with Sloans PT temperature
 readings. I took the PT temp as being correct due to the fluctuation in
 ours), and ice/snow on the enclosure roof kept us closed all night long.
 Roof heaters were kept on all night (and left on when I left).  Hopefully
 they will be able to melt the ice during the day.
