                  ------------- ACTIVITY LOG --------------
   Observing Specialists: J.Dembicky, J.Barentine
   First-half observers emailed a request during the day to run Spicam
rather than DIS during their observing time.  Startup activities began
around 17:45 despite heavy cloud and intermittent rain over APO.
Continued rain, clouds and occasional fog prevented opening entirely.
