Image Details:

Over the solar image of today, an almost perfectly blank Sun, I wrapped the coordinates grid of this day Sun orientation, where the North pole is “P” and Earth’s North is a vertical line through the center of the solar disc; this is to illustrate how Sun and Earth orientation differ cyclically every day of the year except on specific dates i.e. aphelion and perihelion (for the N-S axis)
