              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear all night with good to excellent seeing.  Very productive.  In addition to lots of science, we had the best eyepiece viewing session I've participated in.  There were no problems with the telescope, instruments, or even ARCSAT.
