The 2024 Total Solar Eclipse

  • Released Monday, July 10, 2023

This map illustrates the paths of the Moon’s shadow across the U.S. during the 2024 total solar eclipse. On April 8, 2024, a total solar eclipse will cross North and Central America creating a path of totality. During a total solar eclipse, the Moon completely blocks the Sun while it passes between the Sun and Earth. The sky will darken as if it were dawn or dusk and those standing in the path of totality may see the Sun’s outer atmosphere (the corona) if weather permits.

Making the Map

This map uses datasets from several NASA missions. The eclipse data were calculated by visualizer Ernie Wright using elevation information from SRTM, lunar topography from LRO, and planetary positions from the JPL DE421 ephemeris. The lead visualizer, Michala Garrison, used Earth imagery from NASA’s Blue Marble Next Generation to create the terrain map. Likewise, nighttime Earth imagery from NASA’s Black Marble were used along the path of the 2024 total solar eclipse.

Reading the Map

The dark path across the map is where the largest area of the Sun will be covered by the Moon. People in this path will experience a total solar eclipse. Inside the dark eclipse path are irregular ovals that delineate the Moon’s shadow on the Earth’s surface. For a total solar eclipse, the ovals are called the umbra and create the path of totality. On the map, the ovals contain times inside corresponding to the shape of the Moon’s shadow cast at that time during the eclipse.

Also within the dark path are duration contours. These delineate the length of time totality will last. The closer to the center of the solar eclipse path, the longer it will last. For the total path, times range up to 4 minutes.

Outside the eclipse path, the map displays contours of obscuration, or percentage of the Sun’s area covered by the Moon. Readers can trace the lines to percentages printed along all sides of the map that range from 95% to 10% obscuration. The dark path marks when 100% obscuration begins.
