              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
During checkout, Agile failed with 'Image available too early' error. Running setheartbeat on nimble fixed the problem.
Set KOSMOS camfoc to 2850 for 15.5C.
We had some patchy clouds throughout the night.
Closed at 23:35 due to dust spike. Pollen plates also showed 3-5x particle counts compared to baseline while dust was elevated.
By about 02:00 the dust counts were hovering around the closure limit, but they did not continue to fall off. Along with the elevated pollen counts tonight, we stayed closed. UW03 gave up at 03:40. Dust got worse again after that.
No telescope problems.
