Problems:
An issue with the Hexapod delayed the start of observations until -14 degrees, which meant no twilight fields were observed at the beginning of the night. A light was on in the dome for the first few exposures of the night. SISPI crashed around 21:18 local time, causing 19 minutes to be lost during the reset.

After the three issues noted above, the night was quite smooth and the conditions were excellent.
A ToO was triggered for the first four hours of the night. I observed for both the ToO and the regularly scheduled program, but forgot to change the System Control information after the ToO period until 5:43 local time (close to the end of the night).
