Got this email from Sebastian this evening (19 Oct).  See below that these cleanings were good.

Steve,

I cleaned the radiometers and krypton - there was lots of bird droppings on the upfacing pyranometer. It took 3 kim wipes to clean it all up ...
I started at 15:45 with the radiometers and finished by 15:55 with the krypton. But looking at the krypton plot now I think I made it dirty instead of clean! Maybe I should give it another try in the morning?
It's dark now, so I hope NNE will last through the night. I'll go check on it tomorrow morning, or if it drops out at night.

Have a good night, too!

-Sebastian
