Problems: 

Had slight issue with keeper where it crashed and then we couldn't click on it. No time was lost.

There was some issue with the ra offset so we had to stop for a minute. 

At the very end, the second last script was suppose to run for 16.28 minutes but it finished within 5 seconds and the que was empty because we were waiting for a few minutes to run the last twilight script. Some miscommunication happend between me and the control person and they throught that the observation is done so they closed the dome. By the time I realised the dome is closed and asked them it was too late to open since it takes about 8 minutes to open. Thus I couldn't run the twilight script at the end.
