## Main Question or Discussion Point

If you had your longitude/latitude, and the time/date, how could I go about working out the angle between your normal and the sun?

At first I was doing a simplistic approach of assuming elliptical orbit in only two dimensions and that the earth is a perfect sphere,

Can I get a more accurate method /formula than this that can be evaluated in one step without any iterative methods?

Any help appreciated.
