                 ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Dembicky
 Closed due to wind and humidity.
 2nd Half Observing Specialist: J.Dembicky, R.McMillan
 JMD - Closed until 01:28, when the humidity and winds looked to have
 dropped below our closure limits long enough.  Seeing was horrible, to
 put it lightly.  >3 arc sec.  Not really suprising since a cold front
 came thru and the air was blowing around here quite a bit.
 RM -- Seeing and humidity gradually improved as the wind dropped,
 eventually settling around 1.5 arcseconds by 04:00.  The observer
 was having trouble identifying fields, partly because of the
 humidity but also because he couldn't display the slitviewer images
 properly on his laptop.  I ended up running the slitviewer locally.
 By the time the seeing improved, we had all the problems worked out,
 and everything went smoothly.

      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.
