This photo was taken on the solstice, June 21, 2023. A polar sundial is tilted at an angle equal to the dial's latitude, making it parallel to the earth's axis and perpendicular to the equatorial plane. On the June Solstice, the shadow tip of the gnomon will track along the lower brass hyperbola, which marks the +23.44 degree declination line, the highest arc of the sun for the year. On the December Solstice, it will track the upper brass hyperbola, the lowest arc of the year, -23.44 degrees. A polar sundial demonstrates the beautiful symmetry and cycle of our solar system. Photos, text, and 40 second time-lapse videos of the entire day's shadow course can be found at woodlandpolarsundial.com. Enjoy This Hour !
