              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Rain, alas, not good for tonight's observations.  But very good for the ongoing health of the observatory!  The weather station near the lower parking lot reported about an inch of rain overnight.  And, there was never any chance of getting data.
