                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Barentine
 Opened the enclosure under cirrusy skies around 16:00 to begin cooling.
Chris logged in shortly thereafter and started calibrations at 16:20.
Clouds thickened steadily after dark but we remained open and Chris tried
getting some data.  Clouds became dense enough to warrant closure shortly
before midnight.  We never reopened after that.  By mutual agreement with
the observer decided to shut down at 04:30.
