The Sun's path   

This applet models the Sun's path in a geocentric view, it calculates and visualizes the position of the Sun based on the latitude and the time. It allows to simulate the Sun's position and path during an hour, a day, a month and a year.

For a more precise calculation of the Sun's position, more data are needed that the program does not use, for example longitude, time zone, daylight savings time and the year.

The program simplifies the calculations and uses the average interval between two successive crossings of the Sun over the same meridian. The calculations are referred to the center of the solar disk.

There are some other data to keep in mind for a better compriention of the Sun's path.
