Observing Specialist: C.Gray
After all the fun of yesterday, we were rained out all of tonight :( However, the UW09 class was still forced to learn }:D They hung in there until after midnight like troops. We played with DIS, Echelle, and Tspec. When rotating the tertiary from NA2 to NA1, there was a clamp failure, but then there were no other issues and I did several tertiary changes.

UW06 needed at least an hour of dark time and, when it started raining again at 4:30, I called it quits.
