Total Solar Eclipse of 2017 August 21

On 2017 August 21, a total eclipse of the Sun is visible from within a narrow corridor that traverses the United States of America. The path of the Moon's umbral shadow begins in northern Pacific and crosses the USA from west to east through parts of the following states: Oregon, Idaho, Montana, Wyoming, Nebraska, Kansas, Iowa, Missouri, Illinois, Kentucky, Tennessee, North Carolina, Georgia, and South Carolina (note: only a tiny corner of Montana and Iowa are in the eclipse path). The Moon's penumbral shadow produces a partial eclipse visible from a much larger region covering most of North America.

This special web page contains preliminary information about the 2017 total eclipse of the Sun. It will be updated with more information as eclipse day approaches.

Orthographic Map of the Total Solar Eclipse

The following map shows the overall regions of visibility of the partial eclipse as well as the path of the Total eclipse through the USA. It uses coastline data from the World Data Base II (WDB).

Interactive Map of the Path of Totality

An implementation of Google Map has been created which includes the central path of the 2017 total solar eclipse. This allows the user to select any portion of the path and to zoom in using either map data or Earth satellite data.

Other interactive eclipse maps include those by Xavier Jubier and Bill Kramer.

Maximum Detail Maps of the Path of Totality

The following maps show the path of the 2017 total solar eclipse in maximum detail for the United States and by state. Within the path of totality, curves of constant duration have been plotted for the total phase. Note that the constant duration curves are calculated using the exact shape of the Moon. Mountains and valleys can shorten or lengthen the duration of totality by 1-3 seconds. The maps also include the general terrain highlighting major towns, cities, and highways.

These maximum detail maps were prepared by Michael Zeiler (Esri) using a high level CAD/GIS (Computer Aided Drawing / Graphic Information System) with data provided by Fred Espenak (NASA/GSFC) and Xavier Jubier. These poster-size maps can be saved to your computer for printing. You will have to scale the print size in your printer dialog to fit them to the page size you are printing.
