Waning crescent (~25% illumination)

Summary:
Fairly good night all around. Lost some time early to 
clouds, but was able to fill that with cals and get back
on sky for science observations without much hassle.

Calibrations: 
OSU_CGM - B21721

Details (All times UT):
----------------------------------
01:50 - Test preset MODS1+2
        Sky clearing (daytime thermal clouds, light breeze)

03:00 - Some issues with MODS1 still having collimator covers
	in place, had to do a lock out/tag out to remove them.

03:35 - Moving to standard star Hz44, doing collimation.

04:10 - Hoping to take advantage of good seeing to hit ASASSN17dj

05:15 - Had to abort midway through second exposure after losing guide
	star to clouds. In 30 min exposure we can detect the continuum,
	and we see H-alpha, N II, H-beta, O III.

05:30 - enclosure closed, running cals
        B21721 (OSU_CGM) - ~16 minutes
        M83_F2 (UM_M83) - ~20 minutes

06:15 - Clouds cleared enough to re-open, but still some cirrus.
	Going to go after some bright carbon stars.
	Seeing has been extremely variable during the exposure (ranging
	between 1" and >1.5")

07:10 - Now starting B21721. Seeing started pretty good (~0.8") and got better
	throughout the run (down to 0.6").

09:45 - Going to go after ASASSN18jd to end the night. Decent ~1.2" seeing.

11:00 - Ending observations, as it is past twilight and sky brightness is rising.
