Observing Summary:

Evening started off with grey clouds scattered across the sky. 
We managed to get sky flats, and start observing one target 
galaxy group. Soon, a blanket of clouds made the guide star 
invisible; we lost about 1.5 hours here. Sky then cleared for 
about 1.5 hours, then clouded over for over 2 hours. When it 
cleared partly, we observed two more groups, until twilight 
started around 5:20AM. Fortunately, the humidity levels were well
below what they were last evening.
