              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had lots of high clouds tonight, thin at the beginning and end of the night and thicker in the middle.  I closed for a while during the period where we really couldn't get anything, but all the scheduled programs got some time.  Everything worked well.
