The hottest star in the Big Apple this week is the setting sun.

The annual Manhattanhenge phenomenon is striking twice this week, offering New Yorkers back-to-back shots to watch the setting sun align perfectly with the city grid.

A “half sun” framed by city buildings – and partly cut off at the horizon in a picture-perfect view – will be visible Wednesday at 8:13 p.m., while a “full sun” will be visible Thursday at 8:12 p.m.

Manhattanhenge will be back again on July 11 at 8:20 p.m. and July 12 at 8:22 p.m.

“The key is for an unobstructed view across the grid of Manhattan,” explained Dr. Jackie Faherty, an astronomer at the American Museum of Natural History in Manhattan.

“You want to be as far east as you can get in order to have the full Manhattanhenge effect.”

Fortunately, that means you don’t need to be in its namesake borough to get the full experience.

Here are some of the best spots in the outer boroughs to watch Manhattanhenge on Wednesday and Thursday:

Hunter’s Point South Park in Long Island City is the only non-Manhattan spot that the city Parks Department recommends for Manhattanhenge.

The waterfront greenspace offers unobstructed views of the sun slipping between the skyscrapers, with an added magical bonus of the sunlight bouncing off the East River.

Located less than half a mile north — along the same waterfront stretch — lies Gantry State Park, which Faherty described as her favorite spot to catch the annual phenomenon.

“The nice thing about Gantry State Park is that you’re pretty well in line with 42nd Street or Midtown, and so you can look straight across what is considered one of the best views,” she explained.

“Because 42nd Street is where a lot of people end up going. It’s got a really good long view.”

Perhaps one of the coolest places to catch Manhattanhenge would be atop the walking path on the Queensboro Bridge, which offers views of not just the phenomenon, but of multiple boroughs and the East River.

“I’ve gotten some awesome pictures from people across the Queensboro Bridge,” said Faherty.

Just make sure you’re walking on the bridge — not driving or biking — when you stop to take in the sight.

Unfortunately, there are not many optimal viewing spots in Brooklyn other than its most north waterfront neighborhood.

Greenpoint just makes it within the ideal viewing range for Manhattanhenge.

“From the outer boroughs, you want to be south of 59th Street, north of 110th Street, and then lined up on the grid,” explained Faherty.

Yes, Roosevelt Island is part of Manhattan, but because it is its own island, it offers a different angle to Manhattanhenge than in the middle of Midtown.

The most optimal spot on the residential island would be in Franklin D. Roosevelt Four Freedoms State Park at the southernmost point.

A ride along the Roosevelt Island tram would also provide an amazing view — if you can catch a spot on the uber-popular transit option.

Similarly, the tiny Manhattan island is flush with green spaces and isn’t overpopulated with skyscrapers, making it another prime viewing spot off the Manhattan mainland.

Faherty suggests finding a spot on one of the many islands’ baseball fields for the occasion.

Although it may seem like there are limited hotspots to witness Manhattanhenge, Faherty emphasized that there are countless places to go within the confines of the city.

There are massive crowds on 42nd Street every year — making what she described as a “party atmosphere” — while a few blocks over is much quieter, but offers the same stunning sunset views.

“Every year, I watch it from different streets just because it’s kind of like what your favorite building is. It’s what you want framing the sun,” Faherty said, adding that she asks every year for people to send pictures of their view.

“There are hidden gems waiting for people to find them. I try to collect them every year, but I will say it takes a little bit of ingenuity to find a street that has that kind of perfect setup for you.”

“Look at how many streets there are across the grid. There are probably 160 streets to choose from, maybe more and in different spots … There are a lot of permutations of views, so I would just encourage people to explore.”
