              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Heavy clouds, light sprinkles, and threat of worse during the evening.  By
midnight the sky was clearing, but humidity was too high.  Second half we
were able to take advantage of the warm telescope to get a little time on
sky with very poor seeing, but the humidity didn't properly drop until
shortly before dawn.
