              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The high clouds finally moved out a few hours into the night and we had mostly clear skies after that.  There were some borderline winds around midnight and seeing deteriorated a little but never got too bad.
Varying noise on dcam caused some difficulty with field identification on faint targets but there were enough occasional good images that it didn't prevent observations.
Second half went more smoothly, including some time for fun with eyepiece viewing for the onsite class!
