                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The night started with heavy clouds, nearby lightning, and a few
 sprinkles of rain.  The clouds didn't let up until after 01:00, and
 by then the humidity had popped up.  We were able to open for the
 last two hours of the night as the humidity slowly dropped.  Not
 unexpectedly, the seeing was quite poor.
