LBT OSU/RC Observing Notes
Date: 2015 Oct 15
Observers-- Fausnaugh, Adams

Summary: Opened to partly cloudly skies, which delayed observations.
Sky then cleared (~UT 3:30), and conditions were mostly clear except
for occasional fast-moving clouds (we chose to repeat exposures
affected by these conditions).  Thicker clouds at 10:00 UT, could no
longer see guide stars, but things cleared up for the last 30 minutes
before twilight.

GCS reported sub-arcsecond seeing most of the night.

Completed science targets: 
ND_COSLLS/j2253

OSU_M33/LS5,LS3
OSU_SBqso4civ/q032

UVa_BCD/J0022

Partial programs:

Made an attempt on OSU_ASASSN14jh (very bady clouds, but the trace of
the spectrum is visibile in only 2/3 exposures).


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

00:56 - Opening to partly cloudy skies.

01:30 - acquiring bd284211 (will wait until 12degree twilight ends)
01:41 - observing bd284211 (dual grating and blue channel)
        (seeing ~0.8" GCS GUI, but variable extinction as 
	clouds move through, up to 3 mag)

02:00 - acquiring ND_COSLLS/j2253 (thicker clouds moving in)
      	(guide star is not visible through clouds)

02:13 - closing for clouds
02:40 - reopening-- will try again at lower airmass

02:48 - acquiring ND_COSLLS/j2253 
        guide star is visible, but coming in and out
02:59 - observing j2253
      	(seeing ~ 1.0" GCS GUI, variable extinction, up to 2 mag)
03:21 - clouds are thining
03:35 - sky is clear, seeing ~0.8"
03:51 - extra exposure, because 1st was highly extinguished

04:08 - acquiring OSU_M33/LS5 (bottom source is slightly offcenter, 
      	sending a 1.5 pixel offset to split the difference)
04:22 - observing M33LS5
      	(seeing ~0.9" GCS GUI)

05:29 - acquiring OSU_M33/LS3
05:38 - retaking slit and field images with larger readout 
      	(need 2 objects in slit, but are cut-off at top and bottom for 1kx1k).
05:46 - observing OSU_M33/LS3
        slight delay because red hung at 'exp done, cleaning up' which 
	clashed with observation script (maybe has something to do with 
	manual acquisition images?).  Fixed with 'red expdone' in 
	MODS GUI command line.
06:34 - seeing ~0.9" GCS GUI

06:57 - acquiring UVa_BCD/J0022
07:09 - observing J0022
      	seeing ~0.8" GCS GUI
07:42 - light cirrus moving in (tail of exposure 2/exposure 3).
07:57 - patchy clouds moving in (exp. 3 affected)
08:07 - lost guide star
08:13 - script completed, running two more exposures (guide star has
      	 returned, still up to 2 mag of extinction)

08:43 - acquiring OSU_SBqso4civ/q0321 (bad weather target)
08:55 - observing q0321 (several mags of variable extinction)
      	seeing 0.8" GCSGUI
	conditions have considerably improved over 2st exp (<1 mag extinction)
09:32 - cirrus has moved out for 3rd exposure (more likely to come)
09:41 - 1 more exposure, because 1st one was poor conditions
09:47 - clouds are coming back (lost guide star)
        (guiding coming in and out)

09:58 - acquiring ND_COSLLS/j0800 (clouds continue to move in)
10:10 - observing j0800
      	seeing is 0.8", but lost the guide star just as exposure started
	No spectrum in first exposure, moving to backup weather target

10:31 - acquiring ASASSN14jh (guide star is in and out, maybe it will work)
      	nothing in acquisition image, retrying
	samething, doubling exposure
	still nothing, trying the last bad weather program

10:45 - acquring NGC2617
      	No visible stars

10:54 - back to ASASSN14jh (can only wait to see if stars appear)
11:09 - finallty found a guide star
11:16 - nothing in field image again, retrying at double exposure
11:23 - with double exposure in through image, there maybe something 
      	in the slit (based on a projection region)
11:23 - started .obs script, for what it is worth 
      	(clouds are starting to clear).
	GCS still reports 1" seeing
11:37 - sky is improved for begining of second exposure
      	There is a spectrum there, however faint

12:03 - acquring g191b2b (standard)
12:08 - observing g191b2b, dual-grating and dual channel

12:30 - done, closing for the night.
