Problems: 

First half: images out of focus and trim values not updating (Trim=0). We restarted SISPI and this time Trim got the expected value. We could have also change the value of Trim manually to 1000 but since it was still twilight, we had time to try with a SISPI restart, which solved the problem.

Comments: 

First half: terrible seeing!
