Problems: 

Slightly rough start to the night. The script for the evening asteroid fields didn't work. It looks like the problem was that there is no 'earlyTime' keyword for the observations in the json file. Unfortunately we didn't realise this until it was too late to get the evening twilights, but I will take them in the morning. I checked the morning script and it already had the 'earlyTime' keywords in, and the times for that and the 'lateTime' look sensible.

We also realised at the beginning of the night that the DECAT git repository wasn't up-to-date, so I had to pull the latest version from git to get the correct directories for tonight. I'm not sure if this is normal or not - I know it's usual to pull the latest version of the regular programs directory for a given night, so perhaps this is just a difference between doing DECAT and doing a different program.

 

20:50 - Lost 13m figuring out that the last image of YSE 428 and all of YSE 376 were too west (though we were running on time). Skipped those targets.

22:30 - There was an amplifier fault, but it only seemed to take ~1m to resolve.
