                ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Dembicky
 Clouds and Humidity kept us closed until 22:30.  At 23:15 the humidity
 went over the closure limit and it looked (on IR radar) that something
 was forming to our west and headed this way).  I closed at 23:15, My
 observers didn't get any useful science because of the weather.
 Although the IR satellite images looked like the system was moving out
 (and clear skies would soon be here) the humidity stayed up near 100% for
 the 2nd half with fog and orographic clouds overhead.  We called it a
 night at 05:30 as the humidity was still over the closure limits and
 there would not be enough useful time to get any science, if we could
 open.
