MANHATTAN — It’s that time again: the sun-meets streets phenomenon of Manhattanhenge returns this weekend for what skygazers hope will be another spectacular showing.

Each Manhattanhenge – when the sun aligns with the borough’s grid, lighting both the north and south sides of every street – is made of two nights. During the first night, half of the sun’s disk sits above the horizon, and the other half below. On the second night, the entire disk floats above the horizon.

The year’s first henge will take place on Sunday; the sunset is at 8:12 p.m. An encore will happen the next night at the same.

If you miss the holiday weekend showing, there’s another in July — specifically on the 11th and 12th of that month.

Skygazers should position themselves as far east in Manhattan as possible. The best viewing will be along 14th, 23rd, 34th, 42nd and 57th streets, and at the Empire State and Chrysler buildings.
