Night Assistant:

Problems: 

Afternoon calibrations failed. I restarted Chiron GUI before starting the observations as it was unresponsive.

Lost telescope’s zero point at 1:40 UT, back at 2:00 UT. 

Comments: 

TYC_1569-1212-1 stopped at 1012 seconds because of thick clouds.

Last 2 targets skipped because there were thick clouds in that part of the sky. Clouds advance rapidly and cover most of the sky so I decided to close (9:30UT). After half an hour it was mostly clear but there was not enough time to finish one target.

Seeing data from RINGSS.
