                 ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I started cals around 19:07 and opened when I finished around 19:45.
 Focused the telescope around 20:30 and was on the first target a little
 before 21:00.  John Barentine came in around 22:00 to help out with the
 UC05 Program.
 I switched over to SPIcam for the 2nd half observer just before midnight.
 Clear skies all night long with no problems.
