When is the next eclipse? See dates for upcoming solar eclipses, lunar eclipses, and transits in 2018 and 2019.
There will be five eclipses and one transit in 2019: three eclipses of the Sun and two of the Moon, as well as a transit of Mercury. However, only the transit and two of the eclipses will be viewable from North America.
What is an Eclipse?
- A solar eclipse occurs when the Moon passes directly in front of the Sun, partially or entirely blocking out its light. Solar eclipses are visible only in certain areas and require eye protection to be viewed safely.
- A lunar eclipse occurs when the full Moon enters the shadow of Earth, which cuts off all or part of the sunlight reflected off the Moon. Lunar eclipses are technically visible from the entire night side of Earth, but during a penumbral eclipse, the dimming of the Moon’s illumination is slight. Learn more about lunar terminology.
- An annular eclipse is a type of solar eclipse. Annular eclipses are similar to total solar eclipses (where the Sun is completely obscured by the Moon), but in an annular eclipse, the Moon's apparent size is smaller than the Sun's, meaning that the Sun is not completely obscured. This results in a very bright ring of light called an annulus.
- A transit occurs when one celestial body passes between a larger celestial body and a third celestial body. For example, when Mercury passes between the Sun and the Earth, this is called a transit of Mercury. Because Earth is the third planet from the Sun, we are able to observe transits of both Mercury and Venus.
2018/2019 Eclipse Dates for North America
January 5, 2019: Partial Eclipse of the Sun. This eclipse is visible from North America only in westernmost Alaska. (It is also visible from northeastern China, Mongolia, Japan, eastern Russia, and northern Micronesia.) In Bethel, Alaska, for example, the eclipse will begin at 3:25 P.M. AKST, reach a maximum (obscuring about 60% of the Sun) at 4:51 P.M. AKST, and end at 6:16 P.M. AKST, with the Sun being very low on the horizon for the entire duration of the partial eclipse.
January 20, 2019: Total Eclipse of the Moon. This eclipse is visible from North America. The Moon will enter the penumbra at 9:35 P.M. EST on January 20 (6:25 P.M. PST on January 20) and leave the penumbra at 2:50 A.M. EST on January 21 (11:50 P.M. PST on January 20).
July 2, 2019: Total Eclipse of the Sun. This eclipse is not visible from North America. (It is visible from eastern Oceania and South America.)
November 11, 2019: Transit of Mercury. Mercury will pass directly between Earth and the Sun on November 11. Because Mercury is so small relative to the observed disk of the Sun, the transit is not visible with just a filter over the naked eye—appropriately filtered telescopes or binoculars are necessary for viewing. The transit will be visible from most of North America from 7:35 A.M. EST to 1:04 P.M. EST (4:35 A.M. PST to 10:04 A.M. PST; it will be in progress at sunrise in mid- to western North America).
December 26, 2019: Annular Eclipse of the Sun. This eclipse is not visible from North America. (It is visible from the Middle East, northeastern Africa, Asia except for northern and eastern Russia, northern and western Australia, Micronesia, and the Solomon Islands.)
