LBT OSU/RC Observing Notes
Date: 2015 Oct 12
Observers-- Fausnaugh, Adams

Summary: Opened to relatively clear skies, light cirrus layer, haze/clouds
along horizon.  Sky was stable all night, seeing near 1"down to  0.7" at end of
night.

Completed 6 programs with MODS, 2 programs with LBC, and 2 monitor targets.

Some technical hiccups with MODS red channel.  Twice, the GUI froze between
exposures.  Time lost was because red and blue channels were out of
sync (~22 minutes).



Completed science targets: 

MODS:
ND_COSLLS/j2255
OSU_M33b
OSU_ASASSN14dc
OSU_SBqsos4civ/q0019
OSU_SBqsos4civ/
OSU_M33LS1

LBC:
OSU_M31Merger
ND_oldsn
OSU_monitor/N672
OSU_monitor/N925

---------------------------------------------------------


UT 01:05 - Opened to a layer of cirrus.  Thicker to the south and east, but
quite thin overhead.

UT 01:39 - acquiring a standard: BD284211
	   seeing 1.0"
UT 01:46 - starting obs script
	   dual and blue grating

UT 02:05 - acquiring ND_COSLLS/j2255
	   seeing 0.9", still have a little bit of cirrus (<~0.1 mag)
UT 02:15 - starting obs script

UT 03:06 - acquiring OSU_M33/M33b
UT 03:22 - starting obs script
           DIMM 0.8", guider 1.1", still have a little cirrus

UT 05:11 - MODS red seems to have gotten stuck after the 4th exposure.
"Abort"ing the red and restarting it.  This will put the red side 1 exposure
behind, so the program will take an extra 20 min.

UT 06:03 - acquiring OSU_ASASSN/ASASSN14dc
	   DIMM 0.8", guider 0.9".  Still have a little cirrus.
	   The supernova has faded and its exact position is unclear from the
finding chart so we are placing the slit on the galaxy nucleus.
UT 06:23 - starting obs script

UT 06:59 - acquiring OSU_SBqsos4civ/q0019
UT 07:12 - starting obs script
	   seeing has deteriorated to 1.3" with a bit more cirrus (~0.2 mag)
UT 07:19 - MODS1R did not update the exposure time.  It hung after taking
another 60s exposure (instead of the 400s listed in the obs script).  We
aborted and manually updated the exposure time.
	   the S/N looks lower than desired -- we'll give it 1 extra exposure

UT 07:52 - acquiring OSU_M33/M33_LS2
UT 07:57 - guider having a hard time.  We think the guide star might be too close to
the edge of the patrol field of view.  Aborting and switching to acquire the
nearby OSU_M33/M33_LS1.
UT 08:00 - also having trouble with this one.  It looks like the collimation
is pretty bad, so the TO is going to collimate on a nearby sky for us.

UT 08:05 - trying again to acquire OSU_M33/M33_LS1
UT 08:15 - starting obs script for OSU_M33/M33_LS1
           seeing 0.9".

UT 09:22 - Reconfiguring for LBCs.

UT 09:34 - Moving to focus field OSU_M31Merger
UT 09:54 - Observing OSU_M31Merger
	   Seeing ~ 1.0" (DIMM)

UT 10:10 - focus field ND_oldsn
UT 10:17 - Observing ND_oldsn
	   Seeing ~ 0.9" (DIMM)

UT 10:47 - focus field OSU_monitor/N672
UT 10:56 - observing OSU_monitor/N672
	   Seeing ~ 0.8" (DIMM)

UT 11:33 - focus field OSU_monitor/N925
UT 11:43 - Observing OSU_monitor/N925
	   Seeing ~ 0.7" (DIMM)

UT 12:10 - focus field OSU_monitor/N2403
UT 12:17 - Observing NGC 2403 (well into twilight, sky is very bright,
                 probably unusable, left in queue.)
	   Seeing ~ 0.7" (DIMM)

UT 12:25 -  Closed.  Cirrus moving in, will do sky flats in the evening.
