Solar Declination Explanation, Calculations and Web Links ... Solar Declination is a measure of how many degrees North (positive) or South (negative) of the equator that the sun is when viewed from the centre of the earth. This varies from approximately +23.5 (North) in June to -23.5 (South) in December.

Solar declination (d, rad) is the angle between the equatorial plane and the straight line joining the centers of the earth and the sun.When the sun is directly overhead at any location during solar noon, the latitude of that location gives the declination.

Solar radiation basics; The purpose of this section is to acquaint the reader with the ... (Note that summer in the northern hemisphere is winter in the southern hemisphere and vise versa.) The declination of the sun is the angle between a plane perpendicular to a line between the earth and the sun and the earth's axis.

Changes in the solar declination angle as the earth revolves around the sun creates cyclic changes in solar radiation. These radiation changes contribute to cyclic weather changes that we call seasons. You can get the solar declination angle for any day of the year at the following site.

Also, we should observe the times when planets or other bodies cross these cardinal points, either by change of direction across the ecliptic at 0 declination or when going OOB or returning from outside the solar path and crossing 23°27.5' of declination.
