              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Dis red biases were corrupted at the start of the night. Since DIS was not on, left it alone in the hopes lower temperatures would cure it. Storm came through in the evening. Rain started at 20:00. Nicfps also failed on checkout, but an expose init brought it back.
Rains remained in the area through 03:45.  Tried to open, had some trouble with the tert and eyelids: email has been sent. Got on sky at 04:00. Clouds. Then new rain on the radar. Gave up at 04:30. After closing, we found more errors with the tert. We homed it, and tried to move it again. Clamping failed on a move to NA2. Russet found a way to kluge it to NA2 for tomorrow's run, and we left it at NA2.
