              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
There was a brief power flicker at 18:07, but it didn't seem to affect anything other than needing to reset the mirror covers.
We had to close due to a dust spike at 22:30 and we didn't reopen for the rest of the night.
Pollen plates:
21:00-22:00: 100/16cm2 = 6.25/cm2/hr.
23:45 - 00:45: 220/4cm2 = 55/cm2/hr. Dust was rising during this time (6k-9k 1.0um counts, 40k 0.3um counts)
02:00 - 03:00: 400/9cm2 = 44.4/cm2/hr. Dust high, 10k-11k 1.0um counts, 50k 0.3um counts.
