Partial solar eclipse

The partial solar eclipse of April 30, 2022, is visible from the southeast Pacific and southern South America.

When and where to watch: The April 30, 2022, partial solar eclipse starts in the far southeastern Pacific near the coast of Antarctica at 18:45 UTC. The deepest part of the eclipse is almost due south of the southern tip of South America at 20:41 UTC. The partial eclipse remains visible for the last location along its narrow path until 22:37 UTC.
Maximum eclipse: is at 20:41 UTC when 63.96 percent of the sun will be hidden behind the moon.
Note: This is a very deep partial eclipse, which will pass over a sparsely populated region of Earth.

The number one rule for solar eclipse observing is to make sure you protect your eyes by using an appropriate filter. Purchase eclipse glasses from the EarthSky Store.

Moon, constellation, Saros

This partial solar eclipse occurs 4.7 days before the moon reaches apogee, its farthest point from Earth.

During the eclipse, the sun is in front of the constellation Aries.

The eclipse belongs to Saros 119 in the Saros catalog of eclipses that describes their periodicity. It is number 66 of 71 eclipses in the series. All eclipses in this series occur at the moon’s ascending node. The moon moves southward with respect to the node with each succeeding eclipse in the series.

Next eclipse and eclipse seasons

The partial solar eclipse of April 30, 2022, is followed two weeks later by a total lunar eclipse on May 16, 2022.

These eclipses all take place during a single eclipse season.

An eclipse season is an approximate 35-day period during which it’s inevitable for at least 2 (and possibly 3) eclipses to take place. The current eclipse season has two eclipses: April 30 and May 15, 2022.

Here’s what a partial solar eclipse looks like

View at EarthSky Community Photos. | Our friend James Trezza in Cedar Beach, Mount Sinai, New York, captured this photo of the partial solar eclipse of June 10, 2021. He wrote: “Solar eclipse 2021! Nothing like perfect timing with a bird flying through the frame during the eclipse.” Thanks, James! The April 30 eclipse will be a partial, but deep, eclipse, similar to the eclipse shown in this photo. But the April 30 eclipse path will not be widely seen, as it falls on a sparsely populated region of Earth.
