CHICAGO — Chicagohenge is happening this week in Chicago.
Thursday is the fall equinox, when the sun is in just the right position to rise and set between buildings on east-west streets.
The phenomenon is hugely popular, especially among photographers, with people packing The Loop to get photos of the sun as it sends rays of light directly down city streets.
The effect — which also happens during the spring equinox in March — will last for several days.
The Downtown area gets the most Chicagohenge photos, as skyscrapers perfectly frame the sunset and sunrise, emphasizing the effect. But the lighting should stream down any east-west street in Chicago, making for unique photos.
Chicagohenge “is a great way to connect with your city and also get a cool picture while you’re at it,” Nick Lake, the Adler Planetarium’s manager of theater experience, said in a March video.
Lake suggested people go at sunrise or sunset on a day when the skies are clear to get a classic Chicagohenge photo.
