              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Suvi Gezari has completed Observer Orientation and training.
At time of checkout the roof was checked for snow.  It was determined that
the snow would be a hazard to the telescope if opened.  Cold temperatures
discouraged use of roof heaters.  Snow program run since 11:30MST to
attempt to get the roof clear.  Wind did not start to pick up until into
the evening.  Humidity stayed above closure limit for the remainder of the
night.
Telescope parked facing South to aid in the melting of snow on the roof.
