                ------------- ACTIVITY LOG --------------
  1st Half Observing Specialist: G.Saurage
Clear skies and high humidity at sunset. Humidity bounced around all
1st half, but was low enough for long enough to open at 8:30pm.
Around 10pm it was popping up above 80% again. I continued watching
it bounce around the closure point the rest of 1st half.
  2nd Half Observing Specialist: B.Ketzeback
The dewpoint split quickly dropped to below the closure limit after
I came on shift. We closed at 00:40. The telescope or air temps did
not change enough for the dewpoint split to allow up to open the
remainder of the night.
I spent the night with various kinds of widget development for a
TUI script I was working on for the obs-specs to do SN service
observing and for an IDL project that I am developing for the new
tycho.
