              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Heavy snow at the start of the night, lighter snow later.  Total
accumulation 2-3 inches with drifts.  Frequent power dips during first
half upset the enclosure controller and made it difficult to keep the snow
program running so I changed the telescope position by hand until after
midnight when the power improved and I could run the automatic program.
Telescope parked facing southeast.
