To illustrate the sweep of the sunset azimuth from winter solstice to summer solstice, I photographed sunset as near as possible to the 21st of each month from Dec 2019 to Jun 2020. This composite image shows several effects on the sunset azimuth due to Earth's axial tilt and elliptical orbit: azimuth change across six months (perihelion to aphelion), azimuth change from month to month, and changes in angle and curvature of the sunset arcs.
