Fellow dialists, The following announcement, posted to Usenet's sci.astro newsgroup last week, may be of interest. It concerns a new website that performs sunrise/sunset/local-noon calculations. No doubt many of you already have software to do this, but this particular website may still come in handy as a check, or as a resource to which you can refer those with just an occasional need for solar data.

Or when it rose in 565 BC? How about the length of daylight a week from Tuesday in Albuquerque, N. M.? Just go to NOAA's solar calculator, now available on the Web. A product of NOAA's Air Resources Laboratory, in Boulder, Colo, the sunrise/sunset calculator went on line two years ago, according to John Augustine, a NOAA meteorologist in Boulder, Colo. The updated version became available this week. "We wanted the ability to calculate solar noon in the field," said Chris Cornwall, a NOAA/CIRES electrical engineer. "That's important when you have instruments that have to be aligned north and south." What started out as a purely scientific device has found favor with people from all walks of life, Augustine and Cornwall said. "We have photographers who use it to take advantage of the available daylight," Cornwall said. "There was also a request from an architect who was working on solar lighting for a building in Hawaii and needed to know when and where the sun would be." In addition to questions from students, Augustine added that they've received many requests from religious people who need to know the exact time of sunrise and sunset for the beginning and end of religious holidays. The original program was developed by Cornwall and Aaron Horiuchi from work started by Chris Lehman. Since the calculator has been updated, Augustine and Cornwall estimate that it's accurate "from 1,000 BC to 3,000 AD."
