               ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 We had one hard crash of agile's icc that locked the observer out of
 newton as well. It took about 30 minutes to aquire data again.
 Shortly afterwards humidity was at the limit and the 2.5m observers
 reported dew on flat surfaces outside. We closed for 30 minutes until
 the dewpoint depression returned to reasonable values.
 There was one servo error on the rotator during a slew tonight at
 UT07:26:01. It was quickly recovered by an axis init rot. No downtime
 is counted for this event.
 No other problems tonight.
