Observers: Kuhn, Garnavich (lead), Pogge
TO: Steve Allanson
SA: none (all snoozing somewhere)

All observers and SAs working remotely

Moon phase: gray (1d past last quarter)

Summary:
   MODS at the start tne LBC. Clear all night with good seeing,
   sub-arcsec (0.6-0.8) most of the night, then degraded to 1+ arcsec.
   Moonrise later now after 1 MODS early-evening target, switched to
   LBC for most of the night.
   
Calibrations: 
  Last of the MODS closed-dome calibrations before sunset, only
     SDSS r imaging flats for OSU_ASASSN remaining to be done
  LBC sky flats at dawn


Executed Programs: 
  OSU_CHAOS - N6946 (MODS)
  OSU_Dwarfs -  KK14, N672dwC (LBC)
  OSU_Monitor - N6946, N925, N628, N672, M82, M81, N3077, IC2574



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

01:00 - opened, configured for binocular MODS, LBCs spun up

01:21 - MODSCalib BD+284211, before astronomical twilight

01:23 - seeing 0.8arcsec left and right

01:50 - started red-only standard script

02:00 - started dual standard script


02:12 - OSU_CHAOS N6946LS

02:15 - guide star a double, Rick was ready with an alternative

02:30 - putting it on slit - HII region with a complicated structure,
        centered on a bright core.  Seeing ~0.75-arcsec

03:20 - seeing staying about 0.7-arcsec

03:50 - seeing down to 0.65-arcsec

04:45 - done with N6946LS

*** Reconfiguring Telescope for LBC ***

04:50 - configuring for LBC

05:05 - OSU_monitor/N6946 focus

05:15 - red and blue converged quickly

05:20 - starting OSU_monitor/N6946 

05:40 - seeing about 1.0-arcsec

06:00 - OSU_monitor/N925

06:05 - focusing/collimation and copointing

06:15 - running the LBC script, seeing 1.1-arcsec

06:35 - OSU_Dwarfs/KK14

06:40 - collimation + copoint 

06:50 - LBC script started. Worried about going above 80deg elevation

06:57 - first image FWHM=3.8pix in blue, red is terrible, needs
        recollimation

07:05 - back to focus field for collimation

07:12 - headed back to science field

07:20 - red images still not round, blue looks great. Not clear why red
        is not collimating

07:50 - red got a bit better toward the end

08:05 - done

08:07 - OSU_monitor/N628

08:20 - collimated and copointed

08:29 - first red image 3.77pix FWHM

08:53 - done

08:58 - OSU_Dwarfs/NGC672dwC

09:05 - collimation and copointing

09:10 - start LBC OB

09:20 - image quality in red gets better further south FWHM=3.9pix

10:03 - done. images degraded over the series of exposures

10:05 - OSU_monitor/N672

10:11 - collimating and co-pointing

10:23 - first images look good, 3.44pix FWHM in blue

10:40 - hydrostatic bearing lost pressure, LBC program stopped LBC OB
        had not done V-Bessell. Olga edited the script to finish the
        V.

10:55 - hydrostatic bearing died again. Restarted the V exposures again.

11:15 - done with the extra V exposures

11:17 - OSU_monitor/M82

11:24 - collimation and co-point

11:30 - starting M82 OB. Image quality poor, stars are 5pix FWHM and
        not round

11:40 - OSU_monitor/M81

11:45 - collimated, no co-point (so close to M82)

11:53 - images look ok. 4.9pix FWHM 

12:00 - OSU_monitor/N3077 (short move)

12:01 - collimation was fast. astronomical twilight

12:09 - images not great FWHM=5.3pix

12:15 - OSU_monitor/I2574 

12:19 - collimating on I2574, no co-point

12:26 - first images puffy, FWHM=6.5pix, sky getting bright

12:32 - moving to blank field for sky flats

LBC Sky flats:
  5 V & R at PA=0 and and 3 at PA=180
  5 B & R flats at PA=180
  12 SDT_Uspec flats at PA=180
