              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out mostly clear.  As night set in, there persisted a thin haze, and seeing was less than ideal. Absent any dangers to the dome, we stayed open. There was a problem during CU03's program, we lost contact with the NA2 rotator controller, image-taking had to be paused while problem was addressed.
Seeing and transparency improved a great deal between 3 and 4. Clouds started coming in again around 5:00 but the observer was able to observe to the end.
