 Observing Specialist: J.Dembicky
 Happy New Year!!!
 AZ Velocity Scale  Was:  596.0  Measured:  591.76 Changed to:  591.0
 Alt Velicity Scale Was: -636.0  Measured: -638.37 Changed to: -638.0
 Pre-empted NICFPS to get AGILE (no Focal Reducer) data during EN02 time
 tonight.  We got UBVRI standards with the focal reducer removed.  This
 took a little over 2.5 hrs
 Agile lost communications once tonight (after we finished the on sky
 stuff).  We power cycled the instrument and that cleared things up.
 Seeing was poor and variable for much of the night (especially 2nd half)
