              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
At checkout, kcam and kosmos failed. Seems to have been caused by improperly restarting tron from tagged version instead of trunk version for kosmos. Restarted from trunk version and that fixed things.
TUI disconnected on me on obsA at 05:10 with a connection error.
Thin clouds in and out all night, but we had pretty good seeing.
Pollen counts were about 77/hr at the start of the night at 41/hr in the middle of the night.
