                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Camron Hastings
 Work this afternoon restored functionality to both the tertiary and
 the mirror covers. We opened a little late, around 17:00 and all
 systems came up fine. No problems encountered.
 2nd Half Observing Specialist: Jack Dembicky
 Everything ran smooth as clockwork tonight. Seeing was sub arc sec when
 the FTS folks did a spot check around 03:30 (I also focused the guider at
 this time and had sub arc sec seeing with it as well).
