                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
There was a few inches of powdery snowfall earlier in the day but
when I checked the roof there was no evidence of ice or snow on
the rails or roof. When I did open however the left door did make
some noise like it was rolling over some ice accumulation. There
was no problem opening or closing the dome other than this unusual
audible.
It was a night of watching the dewpoint rise and fall erradically.
The dewpoint split stayed large enough that we did open for a few
hours. This occured a short time after the first half observer
(UW12) gave up for the night and went home. He had a small family
emergency so turned the rest of his time over to me which I used
to test TUI 1.3a11 and a request to please test a fix to PR#537.
I did this test but found additional troubles with this version and
was forced to revert to 1.3a9. The second half observer had just got
into the swing of things and was collecting lots of good data
when the split again became too close and we closed for the rest
of the night. One item to note: Nicfps darks were all zeros in
FS=0, 1 and 2 during checkout again tonight and I needed to stop
the ics, restart and then reconnect the hub. Data was fine after
this.
