Summary:
=========

  High cirrus at sunset.  Seeing was moderate at beginning of the night (0.8").
  We were briefly clouded out by an incoming weather front for approximately
  20 minutes at starting at 2010.  Image quality degenerated steadily after
  the clouds dissipated and became poor (1.5-2") by midnight.  We attempted to
  switch to LUCIFER beginning at approximately 0130 to observe targets with 
  looser seeing requirements, but ran into technical difficulties.  The 
  re-configuration finished by 0210 but the AGw failed when we attempted to 
  send a telescope pre-set from the LUCIFER control panel.  We lost a total of
  4 hours due to this error.
