              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had varying high clouds for much of the night, but most of the time they were thin overhead.  Good seeing at the beginning of the night and moderate seeing at the end of the night contradicted the measurements made by Cyclops, but we only had the three official measurements at time of focus.  Telescope and instruments all worked well.
