Hello
Concerning my previous question about "declination by calculation" I received several useful answers. They all lead to the same formula. Since different people took different approach a had a very good opportunity to learn a lot. Some just gave me a formula (which was what I expected at first); some offered more background information (which was great). I think I have thanked everyone that helped me in a private message. Here I say "thank you" again for each one of you that helped me. And now one more question from a inquiring neophyte: What is the formula to calculate sunrise and sunset times given latitude, longitude and declination (or perhaps the date)? Thank you. - fernando -- mailto:[EMAIL PROTECTED] http://www.pix.com.br Fernando Cabral Padrao iX Sistemas Abertos [EMAIL PROTECTED] [EMAIL PROTECTED] Fone: +55 61 321-2433 Fax: +55 61 225-3082 19º 37' 57.0" S 45º 17' 13.6" W 15º 45' 04.9" S 47º 49' 58.6" W
