              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The ARCTIC ion pump controller had problems again in the afternoon, so it was switched over to one of the older Varian controllers.  This cost no telescope time.
There were more clouds than the forecast anticipated, and also radar getting close, so I closed the covers for a period during first half.  During second half the clouds improved, but seeing was not so hot.
Aside from the ARCTIC ion pump, everything worked well and the Colorado class got a good introduction to observing.
