                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 First half was a welcome relief from the weather of the past week:
 clear, light winds, apparently good seeing (we were getting video of
 the moon -- not conducive to quantitative measurements, but it
 looked great), and LOW humidity.  But of course it couldn't last;
 after the program changeover the humidity rose steadily until it
 reached the limit, then began to waffle around just to make everyone
 as miserable as possible whichever decision was made.  We spent some
 time closed that probably should have been open, and some time open
 that probably should have been closed.  Maybe it balances out.
 What we really need is a dewpoint sensor that looks 15 minutes
 forward in time.  That would be a good investment.

     Note: the wind was coming from the azimuth listed.  The convention
     used is north=0 degrees, east=90 degrees.  The dust count is
     particles > 1u per 0.1 cubic feet.
