followed by mostly poor-weather MODS programs to try and
salvage something useful from the back half.

Calibrations:
B&R LBC twilight flats (to account for shadow feature)
Dual grating + red + blue MODS standard Feige 34

Details (All times UT):
----------------------------------
00:45 - Taking some twilight flats.

01:30 - Starting with OSU_monitor/N672.
	Seeing started <1" but got worse
	as the focus deteriorated. We
	decided to pause to refocus, which
	got us down to about 0.6" (!)

02:30 - Moving on to OSU_LBCSBF/AGC748778.
	Seeing started at ~0.9", but we
	needed to refocus halfway through
	the exposure sequence to get it back
	down to ~0.9".

04:00 - Starting OSU_LBCSBF/KK15. Seeing is
	about 0.7".

04:55 - Moving to OSU_LBCSBF/KK17. Seeing is
	around 0.8".

06:00 - Now switching to MODS as clouds are
	rolling in.

06:35 - About to start OSU_ASASSN/ASASSN19dj.
	A good bit of clouds overhead, 
	evidently causing ~3 mag of extinction.
	Planning to manually execute a fourth
	exposure to compensate for the cloud
	extinction.

08:15 - Moving to OSU_STORM/pg0844, hoping
	its high elevation helps mitigate
	cloud issues.

09:00 - Going to get standard Feige 34.

09:50 - On to OSU_STORM/ngc3227. Measuring
	the guide star indicates about 4.5
	mag of cloud extinction.

10:40 - On to OSU_STORM/mrk142.

11:20 - Starting OSU_STORM/ngc3516. Clouds
	don't look quite as awful as they
	were earlier on the all-sky cam.

11:50 - Moving to OSU_STORM/arp151.

12:30 - Going to get one last target in
	before calling it a night,
	OSU_STORM/sbs1116.
