Titled ‘Manahattanhenge‘ by the astrophysicist Neil deGrasse Tyson, the spectacle marks one of only four such sightings this year when the city’s buildings – positioned in a row 30 degrees east of geographic north – align with the sun’s path. The ‘henge’ part of equation is taken from the sunrises on the summer solstice at Stonehenge, when the sun aligns with many of the stones.
Manhattanhenge — sometimes also called Manhattan Solstice — is unique in that the setting sun is aligned with the east–west streets of the main street grid of Manhattan, New York City. And for all those who wish to get a chance to see this rare dramatic beauty, it will make its last appearance of the year tonight! You will be able to see the half-sun set perfectly between the buildings around 8:21 p.m. tonight.
For the best view of the sun on the horizon, Tyson writes that you should stay as far east as you can in Manhattan and find streets, such as 14th, 23rd or 42nd, that let you see across to New Jersey.
The first Manhattanhenge occurs around May 28, while the second occurs around July 12.
