SunFlower math..
Given
* the logitude and latitude of your position *date * time How to calculate the azimuth and elevation of the Sun position ? NOTE that it is possible to track the sun without knowing explicitly its azimuth an elevation angles. I'm not interested in this. I'm looking for the equations which will return the Sun's azimuth and elevation angles corresponding to given date, time and location. |

All the information you need to calculate this can be found in Astronomical Algorithms by Jean Meeus. I used that reference to write a BASIC program to calculate the altitude and elevation of the Sun at the user's location at any given date and time for an article in The Orrery newsletter, Issue #41. http://members.allstream.net/~gneill/orrery.html |

Dear Greg Heill,
Thank you very much for the references. I'l try to find the "Astronomical Algorithms by Jean Meeus". And I'll also try to find The Orrery newsletter, Issue #41. Kind regards, Miem Chan miemchanATyahoo.com All the information you need to calculate this can be found in Astronomical Algorithms by Jean Meeus.
