              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A beautiful night, photometric throughout with excellent seeing.
We had two failures of ecam while guiding - one silent failure during the "exposing" part of the guide loop at UT 04:00, and one noisier failure which required rebooting the slitviewer computer, at UT 12:20.  Exposures continued throughout and only a few photons were lost.
APOLLO ran successfully with no repeat of the laser dropouts from Saturday night.
