The 2023 and 2024 Solar Eclipses: Map and Data
Making the MapThis 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 MapThe dark paths across the map are where the largest area of the Sun will be covered by the Moon. People in these paths will experience either an annular or total solar eclipse. Inside these dark eclipse paths are irregular ovals that delineate the Moon’s shadow on the Earth’s surface. For an annular solar eclipse, these ovals are called the antumbra and together make up the path of annularity. 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 paths are duration contours. These delineate the length of time annularity or totality will last. The closer to the center of the solar eclipse path, the longer it will last. For the annular path, times range from a few seconds on the outer edge to a maximum of around 4.5 minutes in the center. For the total path, times range up to 4 minutes.
Outside the eclipse paths, the map displays contours of obscuration, or percentage of the Sun’s area covered by the Moon. Readers can trace the lines to percents printed along the left and top of map for the 2023 annular solar eclipse and along the right and bottom for the 2024 total solar eclipse. Notice how the 2024 total solar eclipse has a higher maximum percentage because the Moon will completely cover the Sun’s surface.
