The Solar Analemma over Edmonton

The Solar Analemma over Edmonton June 21, 2013 - June 2, 2014 If observed at the same time each day, in the course of a year, the Sun’s position in the sky traces a figure-8 shaped curve called the “analemma“.

Over the year, the Earth’s axial tilt shifts the Sun’s position north/south and the Earth’s elliptical orbit shifts it east/west. Solstices cor
