              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Since the engineering was all finished last night, tonight was given to
some programs that have lost time to weather and instrument problems.  The
two programs ended up trading some time back and forth across the midnight
boundary to getting setting/rising objects, but since it balanced out and
it was all during bright time, I just accounted it as scheduled.
Tonight was photometric all night with good seeing.  A little bit of smoke
smell came up around morning twilight, but not nearly as bad as the last
two nights.
There were three altitude tracking failures.  The first was in twilight
and didn't cost any usable time; I cleaned some moth guts off the drive
surface.  The second interrupted an exposure; I opened the controller box
to let it ventilate better.  After the third failure I just restarted the
axis and it was okay, but it still caused some delay.
