47 days to total solar eclipse. Eclipse fun facts

A total solar eclipse will cross North America on April 8, 2024. Join us for a countdown! In this episode, Marcy Curran shares some fun facts of solar eclipses. P.S. If you like our videos, please share them and subscribe to our YouTube channel.[/caption]

Act fast if you want reservations for places to stay near the path of totality of the total solar eclipse of April 8, 2024. After this event, we won’t have another total solar eclipse visible from the contiguous U.S. until 2044! The eclipse path will sweep across North America, Mexico and eastern Canada. A partial solar eclipse will be visible over North and Central America.

Total solar eclipse

Partial eclipse begins: at 15:42 UTC (11:42 a.m. EDT) on April 8.
Total eclipse begins: at 16:38 UTC (12:38 p.m. EDT) on April 8.
Greatest eclipse: at 18:17 UTC (2:17 p.m. EDT) on April 8.
Total eclipse ends: at 19:55 UTC (3:55 p.m. EDT) on April 8.
Partial eclipse ends: at 20:52 UTC (4:52 p.m. EDT) on April 8.
Note: The instant of greatest eclipse – when the axis of the moon’s shadow cone passes closest to Earth’s center – takes place at 18:17 UTC (2:17 p.m. EDT). It’s a relatively long total eclipse with a duration of totality lasting 4.47 minutes.

Remember that the number one rule for solar eclipse observing is to make sure you protect your eyes by using an appropriate filter.

Moon, constellation, Saros

Greatest eclipse takes place one day after the moon reaches perigee, its closest point to Earth for the month. During the April 8, 2024, eclipse, the sun is located in the direction of the constellation Aries.

This eclipse has a magnitude of 1.0566.

The Saros catalog describes the periodicity of eclipses. The eclipse belongs to Saros 139. It is number 30 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 total solar eclipse of April 8, 2024, is preceded two weeks earlier by a penumbral lunar eclipse on March 24, 2024.

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 two (and possibly three) eclipses to take place. The next eclipse season has three eclipses: September 17-18, October 2 and October 17, 2024.

Eclipse maps from Great American Eclipse

Michael Zeiler of has generously given us permission to share his eclipse maps for the total solar eclipse. Here you can get a better idea of where you’ll want to be and when to see this unique phenomenon.

Everyone in the contiguous United States will see at least a partial eclipse on April 8, 2024. But those in a swath that extends from Texas to Maine will see a total eclipse. Image via

View larger. | This is the path of totality for the solar eclipse on April 8, 2024, containing the names of cities inside the path of totality. Keep in mind, however, that the cities on the edges of the path will see totality for just seconds, while those at the centerline will see totality for up to up to 4 1/2 minutes the farther south they are. The centerline at the northern end of the eclipse will see totality for just under 4 minutes. Image via

Which location is closest to you?

Maps for the timing of the eclipse

View larger. | It’s not only important to be under the path of totality for the total solar eclipse, but you want to be as close to the centerline as possible as well. That makes the difference between seeing the total solar eclipse for just seconds, versus seeing the total eclipse for more than 4 minutes, depending on your location. Image via

How long will the eclipse last?
