                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Barentine
 High humidity and clouds prevented opening.  During checkout the
telescope failed to slew in altitude and a fault in the encoder was
suspected since it failed to read a position change even when the
telescope was moved by hand.  Craig and Jon Davis replaced the encoder
with a spare.
 2nd Half Observing Specialist: R. McMillan
The sky cleared nicely second half, but the humidity refused to drop.

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