              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Once again we had threats at start of night, an open period, threats in the middle of the night, and then a little window at the end.  Seeing was somewhat better tonight but not consistent.  The missing telescope temperatures also caused some wide focus swings in the evening.  Otherwise, everything worked well.
