Andrew,I don't know whose law that is, but the corollary is this: "It will also be clear on Thursday before the star party." This happened to Joe Goss and me at 5 mile meadow. (You know, "the Seniors Stargazers", or those without regular day jobs.) On Thursday it was very clear, but the rest of the weekend was a bust.

I am sure that someone has told me the reason why the sky is so good after a star party. As this year comes to a close I seem to recall that Sunday night is always better than Saturday night. And the next scheduled star party will tend to show clouds moving in around Friday afternoon. Is there a rule of nature or a mathematical formula to explain this? See for you self.http://www.saguaroastro.org/content/clocks.htm Why can't we have this on the weekends? Just getting cranky with old age.
