Early NYC risers are in for a treat on Thursday morning.

The sun and Earth have aligned for a very rare “reverse” Manhattanhenge where city streets turn into a perfect viaduct of sunlight as the solar object fits perfectly between skyscrapers.

If you’re down for the early wake-up call to enjoy this natural spectacle, here’s what to know.

Unlike the traditional Manhattanhenge that appears westbound in late spring and summer evenings, this lesser-known “reverse” rises from the east and offers a much shorter duration, according to the Farmers’ Almanac.

It also draws less attention due to typically chilly temperatures, early hours and its shorter duration.

As the sun rises locally at 7:11 a.m. on Thursday, it is around that time when viewing at a street level will be optimal, according to the almanac.

Unlike its more popular counterpart, fewer locations are providing a dynamic shot of this sunrise as opposed to the sunset version. The almanac recommends the intersection of 41st Street & 5th Avenue.

Spots around the Weehawken waterfront in New Jersey — which is opposite 41st Street across the Hudson River — may also provide nice views.

As for the upcoming main event this spring and summer, half-sun Manhattanhenge will be on May 29 at 8:13 p.m. and July 12 at 8:21 p.m.

The full ones will occur on May 30 p.m. at 8:12 p.m. and July 11 and 8:20 p.m.

These are the top viewing locations that NYC Parks recommends. Be sure to arrive a bit early.
