For two days every spring and summer, the sunset lines up with Manhattan’s street grid, creating a gorgeous celestial spectacle. For a brief moment, the sun’s golden rays illuminate the city’s buildings and traffic with a breathtaking glow.

“It’s the best sunset picture of the year that you will have in this beautiful city,” Jackie Faherty, an astrophysicist at the American Museum of Natural History said to The Times in a 2017 interview. “Sometimes they call it the Instagram holiday.”

Manhattanhenge’s name is a homage to Stonehenge, the monument in England believed to have been constructed by prehistoric people and used in rituals related to the sun. During the summer solstice, the sunrise there is perfectly framed by its stone slabs.

Many New Yorkers gathered on Friday at major intersections and gazed to the west as the sun aligned with the grid. It was an improvement over May, when Manhattanhenge was interrupted both nights by heavy rains and cloudy skies.
