About the 2023 and 2024 Solar Eclipses

  • On Saturday, October 14, 2023, the moon is centered in front of the Sun, but only 90% of the solar disk. The remaining 10% will appear as a "ring of fire" around the Moon's silhouette. This annular solar eclipse will be visible within a roughly 125-mile-wide path from Oregon to Texas and on into Mexico, Central America, and northern South America. Most North Americans outside the path will experience a partial solar eclipse.

  • On Monday, April 8, 2024, the Moon will pass directly between Earth and the Sun, creating a total solar eclipse. The new Moon will fully block the Sun’s bright face, turning day into night for several minutes and revealing the magnificent solar corona, our star’s wispy outer atmosphere. Our natural satellite’s dark shadow, about 115 miles wide, will cross Mexico, sweep from Texas to Maine, and then darken parts of Eastern Canada. Outside this narrow path, nearly everyone in North America will get a chance to witness a partial solar eclipse.
