 Observing Specialist: J.Barentine
 Scattered altocumulus clouds around late this afternoon as things were
getting started.  We were open briefly after dark, when it looked like
conditions were sufficient to observe, but then we closed just after 20:00
when there were no focus stars on the guider and some radar returns east
of TorC made me nervous.  Throughout the night the clouds alternately
thickened and thinned, but never became thin enough for us to observe
through.  We did not re-open.
 I had some trouble calibrating the DIS gratings around midnight after the
shift change (the first-half program had a non-standard grating setup that
had to be switched back for the second half program).  Sending out a PR
with the nightlog...
 And last but not least, I have to give a shout-out to my home state of
Arizona, proudly celebrating the 93rd anniversary of statehood.  And you
all thought today was "only" Valentine's Day....
