Yesterday was full sun Manhattanhenge, when the sun set in full alignment with the Manhattan street grid. Manhattanhenge derived its name from Stonehenge, the million years old rocks in South England, where sun aligns according to the tall standing stones. It was a little cloudy yesterday making the sunset underwhelming. The photos of the sunset and the many enthusiasts, watchers and photographers of Manhattanhenge were taken at 42nd Street. Many photographers and watchers gathered on the Pershing Square (Park Avenue) Viaduct. The top photo was taken from last year. The next half-sun Manhattanhenge will be on July 12 (8:25 PM) while the full sun on the grid will take place again on July 11 (8:24) PM according to astrophysicist Neil deGrasse Tyson.
