This is not as trivial a question as one might think, since it is not enough to know the location with respect to the Earth and/or the Sun in some arbitrary coordinate system. One may have to consider things like differences between the solar equatorial plane and the Earth's orbital plane, the changing direction of Earth's spin axis during the year, and the magnetic dipole orientation. ...
