              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had patchy high clouds most of the night, and during the second half of the night there were also some radar echoes that led us to keep the dome closed.  I estimated that in addition to the times the telescope was explicitly closed, the first half observer lost more than half an hour when it was not really possible to try taking data through the clouds.
Everything worked well.  Training of Ted Rudyk continued.
