              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Medium to thick high clouds all night, with some periods of high winds and
high humidity as well.  The 3.5m dewpoint sensor is still misbehaving, so
the dewpoint listed in the weather log below is not reflecting the actual
humidity.
There were also nearby radar blips for much of the night, and a few actual
sprinkles of rain.  But some of the radar may have been overreacting to
clouds, because neither the El Paso nor the Holloman station switched over
to Precip mode.  Perhaps they are understaffed due to the government
shutdown?
While closed, I did some work with DIS on the matter of the shifting slit
masks noted recently, and also adjusted the internal spectrograph focus to
keep up with seasonal changes.
