              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
tspec, while technically good, but showed a strange noise pattern.
We were unable to open due to snow and wind.  There were multiple power outages.  The Snow program was run to rotate the dome but had to be discontinued at 02:30 due to the high winds.  Some snow was blown onto the dome floor through cracks and crevasses around the doors and louvers.
