                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Camron Hastings
 I opened the dome this evening at 15:30 MST to begin cooling. No
 problems encountered in startup. Things ran smoothly all night.
 2nd Half Observing Specialist: Russet McMillan
 Second half was clear and apparently photometric, with excellent
 seeing.  The FTS transition went more smoothly than last night, and
 we were soon on the sky.  There was only a brief delay when the TCC
 got hung up trying to communicate with the improperly initialized
 guider; the software worked normally after a restart.
