Here you'll find some of the best eclipse maps available, as judged by members of the AAS Solar Eclipse Task Force. To avoid overwhelming you with too much information, we've intentionally weighted our listings toward resources that are relatively new, up to date, and/or especially relevant to the August 21, 2017, solar eclipse across America. We've also considered quality, of course; if a map or source of maps is listed here, we think it's of high quality. If it's not listed here, that doesn't mean it's not of high quality — it just means we can't list everything. If you have, or know of, a resource that you think belongs here, please contact us; we can't guarantee that we'll add the item to our website, but we will consider it.
Maps by Fred Espenak, known worldwide as "Mr. Eclipse." Now retired from NASA's Goddard Space Flight Center, Fred is longtime author of the NASA Eclipse Bulletin and the world's leading expert in the science of eclipse prediction.

Maps by Larry Koehn, who for many years has been producing very nice animated eclipse maps and related visuals on his website Shadow & Substance:
Maps by U.S. and State Depts. of Transportation and related agencies, which provide real-time information about traffic, road closures, and road conditions. These resources could prove extremely valuable in the days leading up to the eclipse and on August 21st itself, especially if you're driving into the path of totality:
- Traffic and Road Closure Information
- State-by-State Public Transportation Links
- 511: America's Traveler Information Telephone Number (not a map, but worth knowing about)
Eclipse Calculators are utilities that do one (or more) of the following: search for past or future eclipses at any specified location and/or display detailed circumstances for a particular eclipse at any specified location. Some calculators display results in a table, others on a map:
- Global Circumstances & Animations (H. M. Nautical Almanac Office)
- Interactive Google Eclipse Map & Local Circumstances Calculator (Bill Kramer)
- Local Circumstances Calculator (Xavier Jubier)
- Simulator (UC Berkeley & Google for Eclipse Megamovie 2017)
- Solar & Lunar Eclipses in Your City (TimeandDate.com)
- Solar Eclipse Computer (U.S. Naval Observatory)
- Solar Eclipse Finder (Michael Zeiler & Xavier Jubier for Esri)
