Next Total Solar Eclipse in the United States
The next total solar eclipse visible from the contiguous United States occurs on April 8, 2024. It crosses from Mexico into the U.S. at Texas, travels northeast through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, and New York, and exits into Canada via Ontario and Quebec. Totality lasts up to about 4 minutes 28 seconds along the path. This event follows the 2017 eclipse and will be the last total solar eclipse visible from the Lower 48 until 2044. Outside the path of totality, viewers see a partial solar eclipse.

Upcoming Annular Solar Eclipse in the US
An annular solar eclipse crosses the United States on October 14, 2023. It enters Oregon and California and travels southeast through Nevada, Arizona, New Mexico, and Texas, continuing across Central and South America. Because the Moon is near apogee, it appears smaller than the Sun, producing a “ring of fire” effect. Annularity can last up to about 5 minutes, though most locations experience shorter durations. Observers must use certified solar viewing glasses at all times.

Next Partial Solar Eclipses Visible from the US
Between 2023 and 2044, the United States will experience several partial solar eclipses. Notable events include eclipses on October 14, 2023 (annular, partial phases visible in most of the US) and on April 8, 2024 (partial phases visible across all of North America). Later, a partial solar eclipse occurs on March 29, 2025, visible mainly in northern and eastern sections of the country. Because partial eclipses cover a broad geographic area, many people can observe them without traveling to a narrow path.
- 2023 Oct 14 — Annular with partial phases across most of the US
- 2024 Apr 08 — Total with partial phases everywhere in North America
- 2025 Mar 29 — Partial, primarily in northern and eastern US
- 2026 Feb 17 — Partial, primarily in northern US and Alaska
- 2027 Aug 02 — Partial, primarily in northern US
Lunar Eclipses Visible from the US
Lunar eclipses occur when Earth passes between the Sun and Moon, darkening the Moon or giving it a reddish hue. The next total lunar eclipse visible in the United States happens on March 25, 2026. It is a longer-duration event, with totality lasting about 85 minutes. Followed by a total lunar eclipse on September 7, 2026, which favors western and central regions. Partial lunar eclipses occur more frequently and require no special viewing precautions.

| 2026 Mar 25 | Total Lunar | Totality ~85 min; visible from most of US | NASA/GSFC |

| 2025 Mar 14 | Partial Lunar | Subtle shading visible from North America | NASA Eclipse Website |
Eclipse Types and Geometry
Solar eclipses occur when the Moon passes between Earth and the Sun. If the alignment is perfect and the Moon fully covers the Sun, it is total. If the Moon is farther away and appears smaller, an annular eclipse occurs, leaving a ring of sunlight. When the alignment is incomplete, the result is a partial solar eclipse. Lunar eclipses happen at the full Moon and can be total, partial, or penumbral, with total lunar eclipses producing dramatic red coloration.

Viewing Safety and Best Practices
Eye safety is critical during any solar eclipse. Use eclipse glasses that meet the ISO 12312-2 international standard, inspect them for damage before use, and replace any scratched or torn pairs. Do not rely on sunglasses, smoked glass, or homemade filters. During a total solar eclipse, only remove your glasses during the brief period of totality when the Sun is completely covered. Telescopes and cameras require certified solar filters at the front aperture. For lunar eclipses, no special eye protection is needed.
Practical Planning and Resources
To make the most of an eclipse, determine whether you are within the path of totality (for solar events), choose a location with a clear horizon, and check weather forecasts closer to the date. Plan for traffic, crowds, and limited services along the path. Use official resources such as NASA’s eclipse website for precise maps, timing for your location, and printable eclipse calendars. Apps and local astronomy clubs can also provide real-time guidance and community viewing opportunities.
