              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had thin to medium high clouds and moderate to poor seeing.  The telescope was open all night and observers tried to take data most of the time.  APOLLO got nothing usable but I only counted time as lost when we were sitting doing nothing but watching clouds.
There were still a few hums from the azimuth drives, but no motion errors.  Everything else worked well.
