The October Solar Eclipse Map

In 12 days time people in North, Central, and South America will be able to experience a solar eclipse. On Saturday, Oct 14 an annular solar eclipse will occur which will be visible in some areas of the United States, Mexico, and a number of countries in Central and South America.

NASA's 2023 Solar Eclipse Explorer is a new interactive map which visualizes the path of the solar eclipse on Oct 14 down to the second. The map shows a darkened strip, which visualizes the path of the umbra, the area in which people can experience a total eclipse. You can also turn on a penumbra layer which visualizes where people can experience a partial eclipse.

Everyone living in the contiguous United States should be able to see at least a partial solar eclipse on the 14th. NASA's map allows you to view the percentage of the eclipse you can see from your location. Citizens of New York will be able to see a 23% eclipse. Los Angeles will see about 70% of the sun covered by the moon, and in San Francisco you will get a roughly 75% eclipse.

If you click on a city's place-name label on the map you can view a simulated image of the eclipse from that location, the current weather conditions in the city and the times of the beginning, fullest and end of the eclipse at the selected location. A countdown is also provided showing how much time remains until the moment of maximum coverage for your city.

The map's time slider allows you to see at which times the Antumbra will be visible. This is when the moon passes in front of the sun at your location and you should be able to see a 'ring of fire' around the moon. If you adjust the map's slider you can see the progress of the solar eclipse over the course of Oct 14 and discover when the solar eclipse will occur at any location.
