Next Total Solar Eclipse Across the United States
The next total solar eclipse visible from the United States occurs on April 8, 2024. It enters Mexico and the United States near Mazatlán and crosses 13 states from Texas to Maine before exiting into Canada. Totality lasts up to about 4 minutes 28 seconds, with the longest durations near Torreón in Mexico and in the Great Lakes region of the U.S. Partial phases are visible across nearly all of North America. For U.S. viewers outside the path, the Moon will cover only a portion of the Sun. Key cities in the path include Dallas, Indianapolis, Cleveland, Buffalo, and Montreal. This event follows the 2017 eclipse and is the last total eclipse visible from the contiguous U.S. until 2044.

Annular Solar Eclipse — "Ring of Fire" in the U.S.
An annular solar eclipse crosses the United States on October 14, 2023. The path travels from Oregon through California, Nevada, Arizona, New Mexico, and Texas, then continues into Central and South America. At maximum, the annularity lasts up to about 5 minutes. During annular eclipses, the Moon is too distant to fully cover the Sun, leaving a bright ring visible. Partial phases are seen across much of the Americas. Because this eclipse occurred in 2023, it has already passed, but it remains relevant for comparison and planning future observations.

How to Watch Safely
Never look directly at the uneclipsed or partially eclipsed Sun without proper protection. For solar eclipses, use ISO 12312-2 certified eclipse glasses or handheld solar viewers with CE certification. Inspect filters for scratches or damage before use; do not use if damaged. Alternatively, project an image of the Sun using a pinhole projector or a telescope with a proper solar filter. During totality only, when the Sun is completely covered, it is safe to view the corona with the naked eye, but as soon as the bright limb appears, return to filtered viewing. Avoid using regular sunglasses, smoked glass, or unfiltered optical devices.
Eclipse Types and Geometry
A solar eclipse occurs when the Moon passes between the Sun and Earth, casting a shadow on our planet. If the alignment is nearly central and the umbra reaches the surface, a total eclipse happens; if the Moon appears slightly smaller, an annular eclipse occurs with a ring of sunlight; and if only part of the Sun is obscured, a partial eclipse results. The type and path depend on the distances and geometry of the Sun, Moon, and Earth. Eclipse seasons occur roughly every 173 days, producing at least two solar eclipses per year, which can be total, annular, or partial.
Practical Planning for U.S. Viewers
Whether traveling to the path of totality or observing a partial eclipse locally, plan ahead for traffic, viewing locations, and weather. Arrive early to secure safe viewing spots, bring eclipse glasses for the partial phases, and check weather forecasts. For the April 8, 2024 total eclipse, expect higher demand for accommodations and transportation along the path. Consider travel insurance and backup indoor viewing options if weather is uncertain. Photography tips: use a solar filter for partial phases, remove filters during totality, and bracket exposures to capture the corona and surrounding landscape.
Comparison of Recent and Upcoming U.S. Eclipses
| Date | Type | Path U.S. | Duration |
|---|---|---|---|
| October 14, 2023 | Annular | Western to Southern U.S. | Up to ~5 minutes |
| April 8, 2024 | Total | 13 states plus Mexico and Canada | Up to ~4 minutes 28 seconds |
| August 23, 2044 | Total | Western U.S. | Up to ~3 minutes 45 seconds (predicted) |
Future U.S. Eclipses Beyond 2024
After the 2024 total eclipse, the next total solar eclipse visible from the contiguous United States will occur on August 23, 2044, crossing a path from southeastern Montana down through South Dakota, Nebraska, Kansas, and into Texas. An annular eclipse will appear over parts of Central and South America on October 2, 2024. A hybrid eclipse on March 20, 2025, will be primarily partial for most U.S. locations. Planning now using interactive eclipse maps and NASA’s eclipse calendar helps you prepare for these infrequent events.
