Got this email from Sebastian this evening (19 Oct). It turns out the the krypton voltage increased from about 1.7 to 2.1V, so it should be 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!
