Problems: 

Several times along the night, I had problems with the synchronization between the dome and the telescope. I restarted the dome azimuth in the dome init position each time.

 

At 09:05 UT the dome got crazy, it started to rotate without stopping, I had to turnoff the dome to stop its motion. I do not know the reason of this failure. Due to this technical problem I finished observations.

 

It was not possible to close the dome ventilation door 20 completely.

Comments: 

TELOPS: Please check the dome, it is crazy…

 

Due to clouds along the night, the most of targets were observed with variable signal.
