                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Light fluffy snow on the enclosure and blowing snow kept us closed all
 night long with accumulations of around 4-6 inches.
 Snow program was run all night long and the roof heaters were turned on
 at the end of the night.  Hopefully sunlight and the heaters will melt
 any accumulated snow during the daytime.
