              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
High wind and high dust in the afternoon, but they weren't THAT high.   So it was disappinting when the wind dropped and the dust came down for a single measurement below the limit before bouncing up again for another couple of hours.
Finally the dust went down and stayed down and I opened, then I realized I hadn't been measuring pollen (because I thought it would be mostly dust).  So I set out a plate right after opening, but I think I messed up the pre-cleaning because that plate had very unexpectedly high counts, and other plates measured by both myself and Kaike had lower counts.  So probably the pollen was fine.
Tracking was a challenge for a non-sidereal object at very high declination because of great circle/small circle issues, but we did get some good spectra!
