Moon phase: 
Waxing Crescent (Illumination: 23%)

Summary: Good, productive night, though there were some hiccups at the
         beginning of the night (during ND_lamost) due to technical
         issues with MODS2R, where the GUI would appear to stay stuck
         on starting an exposure.  Other than that, fine.  No weather
         issues.  Seeing was 1"-1.5" at beginning, 0.5"-1" at the end
         of the night.  TI is b

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

00:40 - starting twilight flats with LBC

01:00 - done with LBC flats, moving to MODS

01:26 - started acquiring for feige110
01:37 - started exposures for feige110
        seeing is 0.7" 

01:50 - started acquiring for ND_lamost
02:02 - started exposures for ND_lamost
        seeing is ~1.2-1.3 b/c low on horizon (~34 deg)
        issue with mods2red hanging at "starting 2 of 27 exposures"
        tried "STOP", didn't work 
        "red exp done" started exposures again, but went back to 1 of 27
        exposures

02:41 - mods2r hang up again, "red exp done" worked 
02:43 - mods2b unique image - no files affected
02:45 - mods2r hang up again - skipped to "image: 15 of 27" - may need to do
        extra exposures
02:48 - second mods1 red exposure readout delay; seeing up to 1.3"
03:00 - seeing up to 1.5"
03:06 - mods2r hang up again; this time, mods2r "finished" all
        remaining images in sequence (gui quickly flashed through
        exposures) no apparent issues with actual image files, but
        timing between mods2b and mods2r may be off issue may have
        been caused by a stray terminal generated during modsalign
        exposure sequence for mods2r restarted
03:20 - seeing around 1.3"

03:25 - mods2r "in a state" - gui is not updating properly but log
        seem to indicate mods2r working properly

03:28 - aborted sequence for mods2 after mods2r and mods2b became
        synched in exposures (21 blue, 20 red), reran script for mods2
        only first of new sequence - mods2r*.0035.fits |
        mods2b*.0030.fits

03:38 - issue NOT solved by starting over exposure sequence, began
        manually taking images with mods2r using gui

04:01 - issue may have been due to time series taxing the system
        (though this is unclear)

05:02 - started acquiring for UVa_BCD_MODS/J0117
05:07 - started exposures for UVa_BCD_MODS/J0117
05:32 - seeing around 0.7"

06:05 - started acquiring for OSU_TXS0506 using TXS0506_UT0630.acq (PA = -42)
06:17 - started exposures for OSU_TXS0506 using TXS0506_1h.obs
        seeing around 0.7"

07:30 - started acquiring for UVa_FR_AGN/J0742_27
07:38 - started exposures for UVa_FR_AGN/J0742_27
        seeing around 1"
07:54 - mods2r hang up, comms log seems to be exposing

08:12 - started acquiring for MODSPhotCal/gd71
08:22 - started exposures for MODSPhotCal/gd71
        seeing around 0.6", elevation 70deg, airmass 1.06
08:31 - mods2r hang up 

08:40 - started acquiring for OSU_ASASSN/HD45762obs2 using
        HD45762_UT0830.acq (PA = -18)

08:48 - started exposures for OSU_ASASSN/HD45762obs2
        seeing around 0.8-0.9", elevation 49deg, airmass 1.31

09:00 - started acquiring for OSU_ASASSN/ASASSN19dj
09:13 - started exposures for OSU_ASASSN/ASASSN19dj
        seeing around 0.9"-1.1"
10:02 - seeing around 0.8", some cirrus (~0.1 mag)
10:12 - clouds starting to roll in, up to 2 mag of extinction
10:22 - seeing around 0.6", extinction down to 0.5 mag

11:27 - started acquiring for UVa_FR_AGN/J0800_31 
11:42 - started exposures for UVa_FR_AGN/J0800_31
        seeing around 0.8"
