"Sun-Up at Quorum
This is a solar equinox marker. It is located at Landmark Boulevard and Quorum Drive in Addison, Texas.

At mid-day in the spring and the autumn, when days and nights are equal in duration, the sun’s rays pass through an aperture in the arch to strike the sphere below.

Due to the uneven elliptical course the earth travels around the sun as well as the inclination of the earth’s axis the sun seven minutes late in the spring and seven minutes early in autumn. Twenty-seven minutes must also be added to compensate for the longitude and latitude of Dallas.

March 21st at 12:34
September 21st at 1:20"
