This guide provides links to Government Information about the Great American Eclipse that will occur on August 21, 2017

Favorite Eclipse Sites

Eclipse Safety Infographic from the American Optometric Association - The American Optometric Association has put together a very concise infographic on eclipse safety, information that everyone should know about and follow.

2017 Total Solar Eclipse in the U.S. - is one of many videos that has been put out by NASA’s Scientific Visualization Studio. Page down to see the third video on this page, which has images showing what the sun will look like in a given location.

Geogebra Eclipse Magnitude and Obscuration - A website that allows users to change the radius and center of the moon to demonstrate the relationship between eclipse magnitude (a value between 0 and 1) and percentage obscuration for solar eclipses. For the upcoming eclipse, the moon radius should be set to 1.02. Move the dot on the Moon Centre to the left to show an estimated view of an eclipse with a given magnitude and obscuration. In Macomb, Illinois the magnitude will be 0.956 and the obscuration will be 95.2%. Use the US Naval Observatory Eclipse 2017 (Eclipse Calculator) to determine what the magnitude and obscuration will be in your area.

Interactive Eclipse Weather Map - The North Carolina Institute for Climate Studies, in cooperation with NOAA’s National Centers for Environmental Information, has developed an interactive map that allows users to click on a location to see how often skies at that place are Clear, Few, Scattered, Broken and Overcast.

NASA Eclipse Education - has a very well organized set of educational resources that teachers can use to teach students about the sun and the eclipse. They include both educational materials and activities, such as making an edible model of the Sun and an eclipse viewer.

US Post Office Eclipse Stamps – The U.S. Post Office developed a heat-sensitive set of Forever stamps to celebrate the eclipse, which will occur on August 21, 2017. The stamps show the solar corona with the sun obscured by the moon when cool and the moon when warm. Watch the video of the Forever Eclipse stamps changing that was shot by the WIU Libraries’ Justin Georges.

Eclipses in Fine Art - an article on eclipses depicted in art that appeared in LiveScience. NOTE: At least one of the artists developed permanent eye damage from watching an eclipse.

NASA Eclipse History - provides information on historical accounts of solar eclipses, including one recorded on a Babylonian clay tablet.

Eclipse History (Goddard Space Flight Center) - this eclipse history website from NASA's Goddard Space Flight Center gives quotes from and citations to historical eclipse descriptions.

Astronomy Magazine’s Eclipse Glossary - this glossary gives definitions as well as illustrations of many terms related to solar eclipses.

Espenak, Fred, 2008. World Atlas of Solar Eclipse Paths - this NASA website, developed by retired NASA scientist Fred Espenak, contains links to maps showing the tracks of historical (back to 2000 BCE) and future eclipses throughout the World (to the year 3000). It also contains links to a catalog of eclipses by century and a link to North American Eclipse Paths.

NASA Total Solar Eclipse 2017 - This website from the National Aeronautics and Space Administration (NASA) contains a wide variety of information, including the science of a solar eclipse, a glossary, educational materials and many other resources, including maps and images that can be downloaded and a guide for libraries.

The 'All American' Eclipse: A Guide for Libraries and their Communities - this 24-page guide was developed for libraries by STAR_Net and the NASA@My Library project. It provides general information about eclipses as well as information on companies that sell certified eclipse glasses.
