Today is the annual day of the year when Manhattan's street grid, first laid out in 1811, aligns perfectly with the setting sun over New Jersey. The sun is so aligned that on a clear day it shines down the East-West streets, illuminating both the north and south sides of the streets, a day sometimes referred to as a Manhattan Solstice or, as Neil deGrasse Tyson calls it, Manhattanhenge.

You can look the sun setting in the New York burough at 8:25 p.m. and then be sure to look again for the first FULL "supermoon" of the summer which will appear in the Saturday evening sky.
