APOD: 2024 September 22 – Chicagohenge: Equinox in an Aligned City

Good morning, Rallypoint, and welcome to the September 22nd Fall Equinox edition of Astronomy PIcture of the Day (APOD). We travel to that toddling town today for this glimpse of sunset down Wacker Drive on September 22, 2017. Many US cities are built along a grid of streets that run east to west, matching the Earth's spin axis...hence Chicagohenge. Do you live in one? Go outside a little before twilight tonight, look west, and (assuming it's not cloudy), and you'll know.
