              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had a beautiful night!  Clear, calm, great seeing, and no moth issues!
There was a hiccup with DIS taking every image as if it were a dark.  Russet and I work on this for a time thinking that the shutter was perhaps stuck, but everything checked out.  In the end, a dis init and home solved the problem.
UW05 ended at 12deg twilight and I took the opportunity of grabbing a few Venus exposures with the 50min that was left before dawn.
