              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The night started out with high clouds, high winds, and high dust.  The dust was of course the last thing to come down, and it bounced back up a few times before settling.  Then once I opened it bounced again and teased me by dropping just a little every time I was ready to close.  Finally it stayed down.
Seeing was not too horrible, or would not have been except that too many of the observing targets were at high airmass and/or near the wind in the west.
