                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Russet McMillan
 Snow and fog and blowing snow again tonight.  The snow accumulation
 on the roof from last night was not too bad (considering the
 accumulation on the ground was at least 8 inches), so I continued
 running the snow program all evening tonight even when the snow
 wasn't actually falling, in hopes that the drifts could be cut down
 even further.
 Observing Specialist, 2nd Shift: Jack Dembicky
Snow on the enclosure prevented opening tonight.  Snow program was run
until 05:00. Roof heaters were turned on at 05:00.  Enclosure parked in S.
