Chicago residents will have a reason to take a walk this weekend to experience the phenomenon known as “Chicagohenge.”
Twice a year the sun perfectly lines up with Chicago’s east- and west-facing streets at sunrise and sunset, illuminating buildings with a yellow and orange glow, according to the Adler Planetarium.
The phenomenon starts Saturday and is expected to be seen through Tuesday. On Saturday, the sun is expected to rise at 6:53 a.m. and the sun will set at 7:03 p.m., according to the National Oceanic and Atmospheric Administration’s website.
Tomorrow is Spring! And it's the Vernal Equinox. In this city, it creates Chicagohenge as the sun aligns perfectly with the east-west street grid. #chicago #chicagohenge #vernalequinox #SpringEquinox #weather pic.twitter.com/RgSrlcnbzq

It can be seen during the Spring Equinox and the Autumn Equinox, which is when the planet’s equator receives the most sunlight, according to the planetarium. When that happens, the Northern and Southern hemispheres get the same amount of day and night.
Because of Chicago’s grid system, the sun will set and rise and line up with the city streets facing east and west, according to the planetarium. Anyone can catch a glimpse by going to one of these streets and looking east or west, according to the planetarium.
