OSU/RC Queue Observing UTC 2012 Apr 30
(civil date 2012 Apr 29/30)
======================================

Observers: P. Martini, S. Adams
Telescope Operator: G. Bechetti
Support Astronomer: O. Kuhn

Instrument: MODS

Summary:

  Clear all night, with seeing 0.8-1.1"
  Observed NGC5194_2, NGC5194_3, OSU_Bootes_prism, and spectrophotometric
  standards
  
UT0140

  Experiments with blue prism flats + VFLAT + UG5
  VFLAT 10. + UG5 okay with max 10-12s exposures, although produces an 
  order of magnitude or so fewer counts at the blue end relative to a 1s 
  QTH + UG5 lamp

UT0200 
 
  Opening up to equilibrate temperatures
  Skies are clear

UT0220
  pointing calibration and collimation

UT0233
  acqMODS feige34.acq, seeing 0.8"

UT0241
  execMODS feige34.obs
    -> aborted script after taking the dual grating and red grating images
       because we do not need blue grating and red & blue prims images, but
       forgot to comment out those sections of the OB
  execMODS -b dualPrism feige34.obs

UT0314
  execMODS NGC5194_2.acq
  tried out modsAlign_v116 and modsAlignd
  next aligned with original modsAlign, but had trouble with 
  alignment. This may be because of the 3 stars, 1 is saturated and 1 is 
  outside 5' circle. Although modsAlign seems to be returning an 
  offset PA angle of opposite sign to what it should be 

UT0410
  execMODS NGC5194_2.obs, 0.8" seeing

UT0626
  MODS Dashboard stopped refreshing after the 5th exposure
  aborted the script and then re-ran it to obtain the final exposure

UT0650
  acqMODS NGC5194_3.acq

UT0702
  execMODS NGC5194_3.obs

UT0916
  acqMODS sdss1159.acq
  -> oops, too low
  acqMODS OSU_Bootes_prism.acq

UT0939
  execMODS OSU_Bootes_prism.obs, seeing 1.1" (finished from yesterday 
  with 3 more 1800s, although the last one goes into twilight a little) 

UT1115
  acqMODS bd332642.acq

UT1121
  execMODS bd332642.obs

UT1140
  finished observations... twilight
  starting morning calibrations (flats, lamps, and biases for prism)
