              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Closed at 21:30 due to humidity and clouds forming to our NE and possibly moving this way
We got back on the sky at 03:30 but clouds moved back in shortly thereafter.  I really could not focus the instrument and guider until 04:30.
