Introduction to Sun Position Determination

I have been working on these problems for over 35 years and teaching them for 15. The material here is useful for both determining where the sun is and reading maps. This material will be most useful if you get one of the suggested map reading books and have a computer sun position program such as David Parish's "Sun Path". FAX 818-764-3639 or or or Lenny Abbey's "Sky for Windows" from Abbey Information Systems 404-633-7446 or So far these are the best sun programs I have found. There are some free ones on the net, but these are worth the $100. "Sun Path" comes Mac or PC. "Sky" is Windows, but is also a moon program.

Please let me know if you find other programs.
