NEW YORK (AP) — Twice a year, New Yorkers and visitors are treated to a phenomenon known as Manhattanhenge, when the setting sun aligns with the Manhattan street grid and sinks below the horizon framed in a canyon of skyscrapers. The event is a favorite of photographers and often brings people out onto sidewalks on spring and summer evenings to watch this unique sunset. The first Manhattanhenge of the year takes place Wednesday at 8:13 p.m., with a slight variation happening again Thursday at 8:12 p.m.
