The view is of the sun setting perfectly aligned with the Manhattan east-west grid looking down 42nd Street in midtown. This is an occurrence that happens twice a year and it’s a stunning sight to behold.
“Manhattanhenge (sometimes referred to as the Manhattan Solstice) is a semiannual occurrence in which the setting sun aligns with the east–west streets of the main street grid in the borough of Manhattan in New York City. The term is derived from Stonehenge, at which the sun aligns with the stones on the solstices. It was coined in 2002 by Neil deGrasse Tyson, an astrophysicist at the American Museum of Natural History.” – Source
