              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Heavy clouds and rain for the beginning of the night, then a fairly quick transition to partly usable skies.  Both 3.5m programs and ARCSAT were able to get some data on multiple targets, so a good night was had by all.
