              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Agile error "image was available too early" during checkout. Run setheartbeat on nimble fixed the problem. Also the weather mac froze, so I restarted it.
Dust counters dropped out after 20:00 due to dewpoint sensor errors.
Handheld dust counter 1-micron measurements:
21:30 1400
23:00 1165
02:00 760
04:00 730
We had excellent clear weather all night!
