That will be tomorrow's problem. The best way to store the stuff is to ship it out to the rest of you. Last night's data was fair. It is clear the we need some sort of cloud filter in the pipeline. I think just the mean value of the image does a pretty good job.
Clouds are always brighter here.
Possibly in a really dark location clouds obscure the stars and the mean value goes down. But never here near the city. The clouds pick up the Chicago lights and are brighter than the sky. I am running again with a pretty clear sky tonight. I am slowly accumulating lots of data with WCS headers.
