The event will take place from 1:15 p.m. to 1:35 p.m. in the only solar observatory of its kind on a U.S. college campus. 

In the Page Atrium of the IDEA Center, sunlight passes through the Gnomon Hole in the building’s roof to cast an image on the atrium floor. A Gnomon Hole is an ancient device originally used to compute time. The beam of sunlight will strike the equinox marker at “solar noon,” which is actually 1:34 p.m. CDT, as it moves across the atrium. Markers designed into the IDEA Center’s floor symbolize the scientific contributions of early cultures. The vernal equinox and autumnal equinox are marked by a Chinese symbol, summer solstice is marked by the Greek/ Macedonian symbol for the Sun, and winter solstice is marked by a Mayan symbol to recognize Native American contributions to astronomy.

Dr. David Baker, Professor of Physics, will provide a scientific and historical overview of the spring equinox while attendees witness the progression of the sunlight beam toward the marker, which it will strike at precisely 1:34 p.m.
