                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J.Barentine
 Cloudy, foggy and raining at sunset.  Did a partial checkout in the
18:00-19:00 hour, "partial" in that I did not attempt test slews.  This is
because the relative humidity both in the enclosure and outside was
hovering around 100%, and rather than risk condensing water on the
primary, test slews could be performed later.  The skies cleared somewhat
toward the middle of the half, but the humidity stayed pegged near 100%.
Later, toward the shift change, the skies clouded up again.
 2nd Half Observing Specialist: R.McMillan
 It remained foggy, humid, and/or cloudy for most of second half.
 Around 04:00, I opened the cloudcam, but even if I trusted the
 humidity to stay down (which I didn't), the sky conditions were not
 promising.  The observers gave up an hour before twilight.
