                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: W.Ketzeback
 J.Barentine helped this afternoon with checkout by doing test images.
 Telescope enclosure was open and cooling for two hours before the start
 of the first scheduled program. Weather was clear and air temperatures
 warm at sunset. I mounted SPIcam as a counter weight instrument.
 2nd Half Observing Specialist: R.McMillan
 Everything worked perfectly second half.  I was able to get lots of
 extra work done while the observer obtained lots of good data.  Skies
 remained clear.  Seeing appeared rather poor, but it was hard to be
 sure because the observer was looking at lots of stars at high
 airmass which were bright enough to saturate the slitviewer.

   used is north=0 degrees, east=90 degrees.  The dust count is
   particles > 1u per 0.1 cubic feet.
