               ------------- ACTIVITY LOG --------------
 Observing Specialists: R.McMillan
 Tonight had widespread thin clouds, variable seeing, and rising
 humidity that eventually got me to close early.  I took lots of
 fastcam data.  For tomorrow night, there are no high priority tasks,
 but throughput would be nice to repeat, S-H altitude sweep would be
 nice to repeat, possibly pointing model would be good to repeat; I
 can also try to diagnose some intermittent problems that have been
 cropping up over the past week.  Even if tomorrow is completely lost
 to weather, though, we should be ready for science on Monday night.
