Details (All times UT):
----------------------------------

01:10 - started LBC bias

01:56 - beginning of twilight
	began exposing skyflats (U+R,B+R)
	some saturated, some with counts too low (especially on blue side)
	check over before making skyflats

03:01 - end of twilight
	began observing ND_sn99aa
	seeing around 0.7"-1"

03:42 - began acquiring for OSU_monitor/N3627
	issue with lbcrangebal - couldn't input centers of focus stars
	solved by closing out ds9 and rerunning lbcrangebal (we also dealt with this last night)
03:52 - began observing for OSU_monitor/N3627
	seeing around 1"

04:33 - began acquiring for OSU_monitor/N3344
04:42 - began observing for OSU_monitor/N3344
	started with seeing around 1,3" on red, 1.6" on blue
	got down to around 0.8" on red, 1" in blue

05:14 - began acquiring for OSU_monitor/N3489
05:23 - began observing for OSU_monitor/N3489
	seeing around 0.8"-0.9", somewhat variable
	second to last red exposure read out incorrectly ('~.055615.fits')

06:08 - began acquiring for OSU_monitor/N4258
06:17 - began observing for OSU_monitor/N4258
	seeing around 0.9"

06:55 - began acquiring for OSU_monitor/N4736
07:04 - began observing for OSU_monitor/N4736
	seeing around 0.9"

07:32 - began acquiring for OSU_monitor/N4395
	focus wouldn't converge, so re-ran focus script
	same issue occured after re-running script - issue may have been due to being near zenith (?)
07:44 - began observing for OSU_monitor/N4395
	stars looked out of focus, so re-ran focus script
08:03 - began observing for OSU_monitor/N4395 (again)
	red images are fine, blue images are out of focus (slightly)
	likely an issue with dofpias   (?)

08:18 - began acquiring for OSU_monitor/N6503
	no issues with dofpia
08:29 - began observing for OSU_monitor/N6503
	seeing around 1"

08:45 - began acquiring for ND_oldsn/sn95n
08:55 - began observing for ND_oldsn/sn95n
	seeing around 0.8"-0.9"

09:37 - began aquiring for OSU_monitor/N5194
09:47 - began observing for OSU_monitor/N5194
	seeing around 0.8" in red, but blue stars looked elliptical (issue with not enough pupils in dofpia ?)
	re-ran focusing script for OSU_monitor/N5194
10:11 - began observing for OSU_monitor/N5194 (again)
	blue is better, seeing ~ 0.9" 

10:42 - began aquiring for OSU_monitor/N5474
10:57 - began observing for OSU_monitor/N5474
	seeing around 0.8"

11:33 - began aquiring for OSU_monitor/N4605
11:43 - began observing for OSU_monitor/N4605
	seeing 1" in blue, 0.9" in red

12:?? - made V+R flats
	made B+R flats, some overexposed
