                 ------------- ACTIVITY LOG --------------
              1st Half Observing Specialist: Camron Hastings
   I opened at 17:20 to cool before the first program needed cals. During
a test, the red chip was saturated, but I took about 50 bias frames to
bleed it off. By the time they started cals the chip looked normal.
   The skies were clear and all ran well.
              2nd Half Observing Specialist: Russet McMillan
 The dust counts began to run up shortly before the program change
 into second half.  We stayed open long enough to focus, but had to
 close before getting to any science targets.  The dust counts
 lingered above the limit for several hours before dropping enough to
 reopen.  After refocusing, we got a little over an hour of data
 before twilight struck.

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