The Eta Aquarid meteor shower will light up the sky Tuesday night into Wednesday morning with debris from Halley’s comet, but a bright moon is expected to interfere with viewing, making fainter streaks harder to spot, the Associated Press reported.

During the peak, viewers in the Southern Hemisphere typically see about 50 meteors per hour, though this year’s interference from the moon could reduce that rate by half. In the Northern Hemisphere, skywatchers are likely to see fewer than 10 meteors per hour.

Meteor showers happen when Earth passes through trails of debris left behind by comets or asteroids. As those bits collide with Earth’s atmosphere at extremely high speeds, they produce streaks of light—also known as shooting stars.

Teri Gee, manager of the Barlow Planetarium in Wisconsin, said in the report that Northern Hemisphere viewing will be less impressive and that those farther south should have better odds. “For us in the Northern Hemisphere, it’s not going to be as impressive,” Gee said. “The farther south you are, the better you’ll see it.”

The Eta Aquarids specifically trace back to Halley’s comet, which passes by Earth about every 76 years on its trip around the sun; the next swing by is expected in 2061. The report also noted that while a few stray meteors can appear on any dark night, meteor showers occur at predictable times each year and can produce a more noticeable display.

For viewers trying to catch the show, the Associated Press advised going outside just before dawn and moving away from city lights and tall buildings to get a clearer view of the sky. The report suggested finding a spot that blocks the luminous waning gibbous moon, which it described as 84% full, and looking east near the constellation Aquarius and the bright star Eta Aquarii.

The report recommended bringing blankets and lawn chairs, avoiding smartphone screens, and letting eyes adjust to the dark. “You’re looking for bright streaks that appear in the corner of your eye for a fraction of a second,” said astrophysicist Nico Adams with SSP International, a nonprofit that promotes STEM education.

Gee said there is also a personal payoff to watching in person. “It almost feels like you’re discovering it yourself,” she said.
