Finally, I have Most Blue Skies running reasonably well on one of our servers. Here's the "live" world view:

... with some including current "bluest" sky here.... At the moment, the server struggles to run enough sky calculations to keep the simulation up-to-date. I think it runs about 10 per second. That's on a dual 2Ghz G5 Xserve. We currently have 500,000 places in the database to test which will take about 14 hours to run through. Lets say half of those are in the dark and half or the remainder are under cloud. That's still several hours worth of calculations. So I need to either learn Fortran and improve the SMARTS software for batch processing (not that likely), buy more servers or code some kind of Most Blue Skies @ Home system where the public or sponsors can donate some processing power to the project. Maybe I can find a Fortran to Java translator. That might be a way forward...
