              ------------- ACTIVITY LOG --------------
 Observing Specialist:  R.McMillan
 A clear night with excellent to good seeing.  Collimation
 spot-checks with echelle and APOLLO appeared good.  Everything
 worked well.
 A miscommunication with spotters regarding the APOLLO change from
 the scheduled time led to a delay.  I focus NICFPS during APOLLO
 time while waiting for spotters, and the following observer kindly
 allowed me to run ten minutes over time, which was about how long I
 had spent on the NICFPS focus anyway.  Thanks to this consideration,
 APOLLO was able to observe three reflectors in a near-full phase.
