                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Barentine
 Opened the enclosure at 17:20 under partly cloudy skies to cool as
rapidly as possible in the interest of achieving stable focus early for
the Lens observations and the 1st half program.  I began getting flats for
both lens and the UW program beginning shortly after sunset, around 18:35.
I was able to get the Lens flats and flats for UW in two filters before
the sky became too dark for further flats.  From there I focused SPICam
starting at 19:15 followed by the NA2Gdr and began the short Lens program
at 19:32.
 The clouds began to thicken near the time I handed over SPICam to
Anthony.  Shortly thereafter there was a serious network slowdown which
caused everything on his end to hang for a couple of minutes, but that
seemed to resolve itself.  Meanwhile the cloud situation got progressively
worse.  Clouds began completely clearing from the west around 23:00 and
the sky was almost completely clear by local midnight.
 2nd Half Observing Specialist: N.C. Hastings
   Everything ran smoothly during second half. Clouds moved in around 4am
but did not stop UW's science. Seeing improved as well.
