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 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
