Problem(s) Encountered:

The computer rack A/C is not working.  Kept the computer room door open; over the course of the night the rack temperature climbed to about 75 F.  We left the door to the dome open so the observing room and computer

room should cool off pretty well during the day.

Solutions:

This is a known problem during the winter.  Typically, the system will return to normal functionality after the sun has warmed up the contactors a bit.  Never the less, the computer room AC unit was looked at by the AC techs from Kitt Peak and it is now back working.
