There are also other ways to see the eclipse. You can make a pinhole projector out of paper or cardboard (here’s how), or a spaghetti strainer (with large holes) can be used as a pinhole projector in a pinch, Dr. Faherty said.

Where to Watch It

Viewing the eclipse will be easy from most places in the city, as long as the weather cooperates and you have a clear shot of the sky. But here are a few suggestions:

Parks. Not only can they offer open views of the sky, Dr. Faherty said, but if you don’t have glasses, they are great places to see the eclipse in the sun’s reflection. Look in the shadows cast from nearby trees, she said. “The small amount of space between the leaves can drop little projected images of the sun, which will all be partial eclipses, on the ground.” Or head to a park with a pond (like Central Park, Prospect Park, Flushing Meadows-Corona Park or Van Cortlandt Park), where you can see the sun reflected in the water.

Rooftop bars. For unobstructed views, check out Hotel Americano in Chelsea, which is hosting a free poolside viewing party, or attend the watch parties at City Vineyard at Pier 26 in Lower Manhattan (free, R.S.V.P. here) or the Lovage rooftop lounge in Midtown, Manhattan ($12). Eclipse glasses will be provided.

Times Square. Wait, hear us out. Some researchers say the eclipse is best experienced in a crowd. This way you can better feel the event’s emotional intensity and connect with strangers.
