Cityhenge
An astronomical event in which the orbital position and inclination of Earth are aligned so that the rising or setting Sun is aligned with streets in a city; the Sun shones from the horizon directly down the streets. Noted especially where the streets are aligned with skyscrapers, e.g. in Manhattan or downtown Chicago. Pormanteau word of "city" and "Stonehenge".
Cityhenge is coming, so be careful when driving east the next few mornings.
