                  ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: Russet McMillan
 The dome was opened for cooling at 16:50 under very thin cirrus.  The
 cloudcam is still inoperative, but Mike Carr believes he has found
 the leak that was troubling us for the past few months.  Shortly
 before sunset, we received notice that a GRB had been detected with a
 position good to 8 arcminutes.  With Don York's agreement, we
 switched to SPIcam instead of the echelle program and attempted to
 identify an optical counterpart.  This time was accounted to the
 previously approved UC program for GRB-followups.
 2nd half Observing Specialist: Jack Dembicky
 Clouds rolled in around 00:45 and stopped us from doing science for
 about an hour.
 The clouds once again became too thick to observer thru at 05:15 and we
 closed up shop then.
