   Yet again, like last night, tonight's plan was to check to see if the
recent azimuth control work improved pointing consistency, and take a model
if it had.  Off equator drift scanning is on tap once the model is
completed.
   Also like recent nights, the weather prevented us from opening tonight.
It was mostly clear and humid the first part of the night, but there were
storms nearby in nearly every direction.  It clouded over and started
raining here around midnight.  Rain and thundershowers continued for the
rest of the night.  It looks like the monsoon season has started in earnest
about two weeks early.
   One note regarding weather;  the dewpoint sensor was consistently
reporting a dewpoint depression between 1.0 and 2.5 C while it was raining,
even after it had been raining for over an hour.  This seems a little
higher than normal for these conditions.
   We'll try again tomorrow for the pointing model... At least the EC is
already on the telescope.
