Comments (times in UT):

Moon is bright during this subrun!!
23:00: Telescope closed due to thick clouds
23:19: Sunset twilight
23:30: Clouds getting thinner
23:55: Telescope opens
00:15: Issue with Telescope adaptor. Something to do with the guide probe. TOs are working hard to fix it.
00:35: Temporary fix found
04:00: Communication issue with the TO resulted in us believing we were observe in seeing <1.5" conditions, while in reality the seeing was >2.0". This in turn meant mistaken usage of slit of 1" for fmu and foa.
Sunrise twilight: 9:59 UT
