    Science.
                               SYNOPSIS:
                               =========
    'Twas the night before Christmas, and all through the house,
     Not a computer was stirring, not even its mouse.
     Cartridges hung on the telescope with care,
     In hopes that good data soon would be there...
          GENERAL COMMENTS (see Problems below for details):
          ==================================================
   We never opened, due to clouds.
   Eric has put together a cool set of scripts to gather and format
log data.  Very nice!  See separate email message from Eric for
details.
   IOP v3_23_2 has been declared current.
   We got about 100 frames of binned bias data.  Note, that this was
done with the tbars unlatched, but the imager in the doghouse.  This
would not normally be done, but as we were waiting for a thinning of
the clouds to do spectroscopy, it seemed warranted in order to get
the data, and be able to quickly go on the sky should it have
improved.  The tbars were returned to the normal latched (
maintenance ) mode when the bias drifts were finished.

PROBLEMS IN DETAIL:
===================
    When closing up for the night, we found curious marks on the top
of the doghouse.  They looked a lot like tiny hoof prints.   hmmm.....
