A rare black moon will occur on April 30 and cause the first partial solar eclipse of 2022. Black moons are not an official astronomical term, but one common definition of them states they occur when a second new moon falls in a single calendar month. New moons happen when the moon’s Earth-facing side is fully shrouded in shadow and is nearly invisible. This year’s black moon is the only one for 2022.
The black moon’s partial solar eclipse will begin 90 minutes before sunset on April 30. The best place to see the phenomenon is Chile, where the black moon will block up to 54 percent of the sun. Observers farther north will see less of the sun covered, Forbes reports. The event will only be seen from parts of Antarctica, South America, the Pacific Ocean and the Atlantic Ocean, according to People. Astronomy fans in North America can view the event on a livestream.
The black moon will make it easier to see other key features in the sky, including a rare conjunction of Jupiter and Venus, according to Forbes.
