                 ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 Clouds during checkout prevented opening until around sunset.  Things
 cleared out until around 01:00 when some clouds came into the area.  The
 remainder of the night we had passing clouds off and on.  We never closed
 although the clouds would stop science for a couple mins at a time before
 a clearing patch came thru.
 No problems tonight.
