              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds tonight.  It looked like we might have a hole moving towards us around 02:00 but local clouds persisted and a clearing never occurred.
At the end of the night, when I wsa trying to change to TSPEC, I got the following error.  This may be related to PR2065 with the NA2 rotator disconnecing.  I reset the NA2 rotator and this cleared the problem.  Additional details sent to Bill.
