Observing Summary:

We tested a few different mask and lenslet array configurations for CHaS.We also tried to observe some of the same targets from the previous nights with these different configurations.

At the beginning of the night, we had trouble with the mirror supports, which had to be restarted after we contacted Eric. Because of the time we spent troubleshooting, we couldn't observe one of our targets. We also had trouble with MIS, which had to be power cycled a few times over the night.

The cloudy weather jeopardized guiding for a few hours, so we took less exposures than originally intended during the night.
