                ------------- ACTIVITY LOG --------------
Observing Specialists: R.McMillan
A nice clear night with moderate seeing, somewhat variable.  Humidity
was looking like a possible problem in the afternoon but dropped
sharply around sunset.
During checkout I found that tertiary actuator C was off by a large
amount; it had apparently failed a move a couple of nights ago but
went unnoticed since the telescope wasn't being used.  I did some
test moves, which were successful, and with Mark's agreement I homed
the tertiary remotely rather than monitoring in person.  All tertiary
moves tonight were successful.
Telescope and instruments behaved well; APOLLO got returns from
multiple reflectors, but not record-breakers.
