                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialists: J.Barentine
 Clouds kept us closed during most of first half.  Russet came in at about
22:30 and decided to open in the interest of checking pointing after last
night's pointing model of few points.  After that, she handed control of
the scope over to Julie.
 2nd Half Observing Specialist: R.McMillan
 Pointing was adequate according to a partial model that I did.  We
 got going through varying high clouds, but had to close a couple of
 times due to humidity.  Everything generally worked well except for
 one apparent Remark crash of a flavor we've seen before (version
 2.80b, slitviewer control window froze up and would not close
 although the slitviewer itself was perfectly responsive).  I advised
 the observer to quit Remark and restart, and I ran the slitviewer in
 the interim so that only a minute or two of time was lost.
