LBT/OSURC Observing Notes
Date: 2016 April 06 UT
Observers: Jonathan Brown and Donald Terndrup (at Tucson Remote Facility)
Support: Barry Rothberg (on call)
TelOps: Geno Bachetti

Observing mode:
  MODS longslit
  
Conditions:
  Mostly cloudy.  At sunset we could see the brighter stars on the all-sky
  camera, but in no direction is it clear.  The conditions gradually improved
  during the night, so that at the end it was useable (but never photometric).

Completed science targets:
  OSU_BLRqsos/J1139
  OSU_BLRqsos/J1526
  OSU_BLRqsos/J1316
  OSU_BLRqsos/J1347
  ND_BOKS

Calibration stars:

UT 0245
  Feige 34  Acquisition and spectra.
  Blue science images 2-4, red images 4-6.
  Seeing 1.1 - 1.2"

UT 0300
  Moving over to OSU_ASASSN14ae
  Begin science frames at 0315.  Definitely quite a bit of extinction overhead.
  Images are pretty faint.
  Seeing about 1.1".
  Blue image 5-7       Red image 10-12

UT 0422
  OSU_BLRqsos/J1139
  Seeing 1.2-1.4".  Clouds variable through science exposures.  Spectra are very
  faint, so we'll do this twice.  Second time is a reacquisition to move the
  PA to the right parallactic angle.  Sequence is telluric - object - object -
  telluric.  At end of all this, it was clearer than it had been, and the
  seeing at the end was 1.1".  It's still not clear, though.
  Images b.17 and r.31 are no good (observer error running script).
