              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night began rather promising.  We had clear skies and moderate seeing.  However, clouds come on us quick around 23:00 and after losing Jupiter completely, we closed up for a couple hours. We reopen but the clouds persisted until dawn, when it completely cleared up (of course).
No problems tonight.
