                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
Snow, fog, clouds and humidity all night.
I called it a night at 4AM with 2-3 inches of fresh powder on the building we were not going to be
able to open even if it did decide to clear.
Telescope left parked due South.  Roof should be check and snow removed, if necessary.  Snow
program didn't seem to want to slew the telescope after the initial slew so I quit the program and
manually move the telescope about every 30-60 mins.  Unfortunately there wasn't much of a wind
tonight.
