                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: N.Camron Hastings
 2nd Half Observing Specialist: Russet McMillan
 Thick clouds prevented any spectroscopy first half.  Shortly after
 midnight, I noticed that the clouds had thinned somewhat, so I
 contacted the scheduled second-half observer to find out his science
 requirements.  He was willing to give it a try, so we got set up and
 opened the dome around 01:30 under variable cirrus.  We were able to
 get some focus measurements, but even the brightest of the program
 stars was defeated by the combination of clouds plus moon.  The
 observer gave up at 02:40, and while the clouds remained thin enough
 to pose no actual threat, I played around with some engineering tasks
 instead, using very bright stars.  No science was accomplished, but I
 learned some interesting things about the echelle autoguider.

   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.
