              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had clouds and sprinkles in the evening.  When the clouds cleared the radar was still ominous but based on the pattern I expected it to dissipate so I took a chance, and we were able to remain open for the rest of the night.  There were a few cloud patches but we never had to stop observing.
The Agile guider had some trouble due to software changes made for the sake of the DIS slitviewer.  Fritz reverted the software and after that the Agile guider worked well.  No observing time was lost to this problem.
