Problems: 

At the beginning of the night there was a problem with the hexapod. It started at 19:20 and was resolved by 20:33. It was 20:45 when we started science.

Around 04:20 when we re-started observing I found that the seeing had jumped up to 2.5-3". After asking the operator to do a focus run to make sure everything was okay I decided to continue taking data, but I'm not sure if it will be useful to the PI.

At 05:20 the clouds came in again, blanketing the whole sky. We closed for the night at that point.
