EQUINOX SUN SPOT:   

   On the Vernal and Autumnal (spring and fall)) equinoxes, usually September 22 and March 20, the sun's noon angle in Terre Haute reaches  50.5 degrees and aligns with the angle of the sun tunnel . This angle allows sunlight to pass directly through the tunnel, illuminating a marker located on the granite base, signaling the moment in the yearly cycle when the length of day and night are of equal duration.
