                ------------- ACTIVITY LOG --------------
 Observing Specialists: R.McMillan,G.Saurage
 The engineering task list was completed last night, sooner than
 expected.  We let the daytime work continue in the dome right up
 until sunset, then started on some pick-up science programs.
 High humidity did not stop us from opening soon after sunset. Rain
 in the area seemed to be clear. So we opened and let UW02 get in
 some sky time they missed out on the previous few days.
 Mostly clear skies, moderate to high humidity rest of 1st
 half. Seeing was fair, around 1.0" or better.
 Second half had more mediocre seeing and humidity creeping higher.
 It got high enough to warrant closing right about the start of
 morning twilight.
