LUCIFER

Summary:
=========

  Mostly cloudy at sunset, with cirrus and patchy stratus clouds covering 70%
  of the sky.  Clouds begin to clear at approximately 7:00 PM.  Seeing
  was approximately 0.5" at the beginning of the night, 0.4" in the middle,
  and 0.6" at the end.

  We observed:  H2IMG: both BrG & H2 bands
                MWC480: two disk angles (0 & 45 degrees)
                MS 0451:  H & K bands
                IZw18:  complete spectral sequence + telluric standard
                HS0837: complete spectral sequence
                SDSS1309:  complete spectral sequence + telluric standard, no
                           flux standard
                Twilight flats:  H, K, BrG bands
                Dark exposures for all configurations

  We experienced technical difficulties with focusing of the secondary mirror 
  at the beginning of the night.  These cost approximately 2 hours of observing
  time.  We also had difficulty finding guide stars for several of the
  ND_diskangle slit orientations.  These may be related to poor collimation,
  but we are unsure of the exact resolution.

  Setup
=============

  00:12  Sunset
  00:15  Open dome
  00:35  Begin reconfiguring telescope for LUCIFER
  01:19  Finished configuration.  Correcting telescope pointing.
  01:50  Very poor telescope collimation.  Unable to determine pointing.
  02:01  Pointing toward Persson standard and attempting to collimate.

  03:20  John Hill called in.  Secondary mirror is sitting at zero.  Reset
         secondary mirror hexapod.  Image quality improves dramatically.
  03:25  Check telescope pointing.
