Details (All times UT):
----------------------------------
00:45 - Set up and planning to start
	by getting the requested second
	observation of OSU_ASASSN/ASASSN19acc
	once we hit twilight.

01:15 - Noting 1-2 mag of cloud extinction
	and starting observation of 19acc.

01:50 - Getting Feige 110 standard.

02:30 - Sky conditions appear strangely good,
	so we're going to try our luck and go
	after OSU_TXS0506.

02:40 - Starting observation, looks like between
	2 and 2.5 mag of cloud extinction with
	seeing between 1.2" and 1.5".

04:20 - Cloud extinction fluctuated between 2 and
	0.5 mag for most of the observation, with
	an average closer to 0.5.

04:50 - Got blown off preset by wind gusts, so the
	last exposure was lost.

04:55 - Moving to the more northern target
	OSU_ASASSN/PS18kh to hopefully avoid
	further issues with the wind. Cloud
	cover caused us to lose the guide star
	initially, and even after changing the
	script to a 12.5 mag start it still
	failed.

05:20 - The wind wins this round. Gusts are past
	the limit, so we're closing up.

05:45 - Doing slit flats for the 2.4" and 5"
	slits since we hadn't gotten those
	earlier.

06:05 - Getting binned calibrations for the
	ND_paloma program. MODS1 blue hung on image
	5 of 5 ("Starting exposure 5 of 5..." never
	went away in Dashboard). Tried fixing by hitting
	Update, then "blue expdone" but does not appear
	to have been fixed. Eventually got it to work
	by hitting "Go" to take another bias manually.

07:00 - Weather still sucks, so we are closed.

08:00 - Weather still sucks.

09:00 - Weather still sucks.

10:00 - Clouds are getting even thicker, and the
	wind is forecasted to stay gusty for the
	rest of the night, so we're going to call
	it and head out.
