The dramatic spectacle was just the first of the year, and a fuller version of the setting sun is expected to be seen between the city’s famed skyscrapers on Friday.

He was part of an expedition led by Gerald Hawkins, who first theorized that Stonehenge’s megaliths were an ancient astronomical observatory. It struck Tyson that the setting sun framed by Manhattan’s high‑rise canyon could be compared to the sun’s rays striking the center of Stonehenge’s circle on the solstice. Unlike the Neolithic Stonehenge builders, the planners who laid out Manhattan did not intend to channel the sun. It just happened that way." }, { "type": "heading", "content": "When is Manhattanhenge?" }, { "type": "paragraph", "content": "Manhattanhenge does not take place on the summer solstice itself, which is June 21 this year. Instead, it occurs about three weeks before and after the solstice. At these times the sun aligns exactly with the city’s straight‑edge streets." }, { "type": "paragraph", "content": "Viewers get to choose between two different versions of the phenomenon. On Thursday, and again on July 12, half the sun is above the horizon and half below it at the instant the sun lines up with Manhattan’s street grid. On Friday and July 11, the whole sun will appear to hover between buildings just before sinking into the New Jersey horizon across the Hudson River." }, { "type": "heading", "content": "Where Can You See Manhattanhenge?" }, { "type": "paragraph", "content": "The traditional viewing spots are along Manhattan’s broad east‑west thoroughfares: 14th Street, 23rd Street, 34th Street, 42nd Street and 57th Street. The farther east you go, the more dramatic the view as the sun hits building facades on either side of the street. It is also possible to spot Manhattanhenge across the East River in the Long Island City section of Queens." }, { "type": "heading", "content": "Is Manhattanhenge an Organized Event?" }, { "type": "paragraph", "content": "Not really. Seeing Manhattanhenge is mostly a DIY affair. People gather on east‑west streets about half an hour before sunset and snap photos as dusk approaches. That’s if the weather is clear; there’s no visible Manhattanhenge on rainy or cloudy days." }, { "type": "heading", "content": "Do Other Cities Have Similar Sunset Events?" }, { "type": "paragraph", "content": "Similar effects occur in other cities with uniform street grids. Chicago‑henge and Baltimorehenge happen when the setting sun lines up with the gridded streets in those cities in March and September, around the spring and fall equinoxes. Toronto‑hence occurs in February and October. But Manhattanhenge is particularly striking because of the height of the buildings and the unobstructed path to the Hudson River." } ]
