              ------------- ACTIVITY LOG --------------
Observing Specialist: H.Abbot

During afternoon checkout, na2-rotator was throwing warnings and preventing axes from initialising:    text='INIT failed for axis: rot1'
Reset na2-rotator axis controller through talk2boxes and all was well.

No other telescope or instrument issues to report. Minor (known) dome leaks present as 
had been noted in prior nightlogs.

Heavy cloud, high humidity, and high winds kept us closed all night.
