Internet Resources/Databases
arXiv
https://arxiv.org/
The arXiv, a freely accessible database hosted by Cornell University, is a collection of searchable technical material on physics, mathematics, computer science and other subjects. Included with the physics materials are journal articles, white papers and other technical reports in the field of astrophysics.
Citizen CATE (Continental-America Telescopic Eclipse) Experiment / National Solar Observatory
https://eclipse2017.nso.edu/citizen-cate/
The National Solar Observatory created a website for the 2017 solar eclipse with information on solar science and a special project. Citizen CATE was a citizen science project with volunteers manning 68 telescopes spread along the path of totality, capturing high resolution images of the inner solar corona, an area of the sun that is normally overshadowed by brighter areas and thus difficult to observe. This project was just one example using the eclipse as an opportunity for science.
Eclipse Chasers
https://www.eclipse-chasers.com/
As the site name suggests, this site deals with eclipse chasers, allowing users to enter and track the eclipses they have seen. However the site has a great deal more content, from eclipse chaser terminology to historical information on eclipse viewing from the air and sea to links to material from past solar eclipse conferences.
Eclipse Resource Guide/ Astronomical Society of the Pacific
https://www.astrosociety.org/education/astronomy-resource-guides/eclipse-resource-guide/
Andrew Fraknoi created this guide for the Astronomical Society of the Pacific resources relating to eclipses in general and the 2017 eclipse in particular. While listing many of the same sites as other web guides, this guide includes more magazine article references than most. Links to the articles are not included. However, the Library has Astronomy and Sky and Telescope in print and electronically for on-site users.
Eclipse-maps.com
http://eclipse-maps.com/
This site traces the history of eclipse maps in a series of galleries, with images ranging from maps dating back to 1654 to the modern computer data driven maps of today.
EclipseMob / UMass Boston & George Mason University
http://eng.umb.edu/~eclipsemob/
EclipseMob is an example of a citizen science project that was run during the 2017 eclipse. Volunteers made recordings of low frequency radio waves to help researchers study changes high above the surface of the earth in the ionosphere during the eclipse. While the data collection may have concluded the site still has information that may be of interest to students and teachers on eclipses, radio waves and the ionosphere as well as links to other resources.
Eclipses and Transits / NASA
https://www.nasa.gov/eclipse
NASA’s main website has a page with a short overview of eclipses, images and videos.
International Astronomical Union / Working Group on Solar Eclipses
http://eclipses.info/
The IAU, an international organization of professional astronomers and national astronomical societies, maintains a working group to promote eclipse science to the general public and assist in coordinating expeditions. Their site includes links to information on past and future eclipses as well as reference material.
Managing the solar eclipse / California ISO
http://www.caiso.com/informed/Pages/SolarEclipse/Default.aspx
Even in areas not crossed by the path of totality, where the solar eclipse was only partial, the eclipse had noticeable effect on electrical power generation. California Independent System Operator, a California power supplier, produced this page with information on their plans for operation during the eclipse and a report discussing the actual effect on the system.

Mr.Eclipse.com / Fred Espenak
http://www.mreclipse.com/
Fred Espenak, NASA’s now retired eclipse expert, shares some of his images from years of eclipse viewing and advice on eclipse photography at Mr.Eclipse.com. The site also has information on related topics such as eclipse quotations and specially issued stamps. Espenak also maintains EclipseWise.com, a personal eclipse prediction site and other astronomy sites.
NASA Eclipse Web Site / NASA Goddard Space Flight Center
https://eclipse.gsfc.nasa.gov/solar.html
Tables and maps of eclipse paths calculated by NASA astronomer Fred Espenak make up much of the material available at this site, covering solar eclipses from 1900BC to 3000AD. This data was published in Five Millennium Catalog of Solar Eclipses: -1999 to +3000, an electronic version of which is available at https://eclipse.gsfc.nasa.gov/SEcat5/SEcatalog.html. Predictions from 1986 to 2035 are also reproduced in Fifty year canon of solar eclipses, 1986-2035 which is described above. The site also includes NASA’s solar eclipse bulletins, as well as a listing of “Solar Eclipses of Historical Interest,” and links to additional sites.
NASA Technical Reports Server
https://ntrs.nasa.gov/
Hosted by NASA, NTRS provides free access to the journal articles, technical reports, conference papers and other technical materials produced in the course of NASA funded research, including material on solar eclipses.
SAO/NASA Astrophysics Data System
http://adsabs.harvard.edu/index.html
The SAO/NASA Astrophysics Data System maintains records for millions of journal articles in astronomy, astrophysics and physics. Entries have abstracts, references and citing articles. Most records have links either to the full text or to a source with the full text article, although sometimes that full text is behind a paywall. In some cases the record includes links to data as well.
Solar Eclipse Across America / American Astronomical Society
https://eclipse.aas.org/
The American Astronomical Society maintains a page on eclipses and eclipse viewing. The site has a prominent section on eye safety and links to a variety of resources including books, educational materials, images, maps and more.
Solar Eclipse Calculator & Diagram / Xavier Jubier
http://xjubier.free.fr/en/site_pages/SolarEclipseCalc_Diagram.html
Eclipse chaser Xavier Jubier created this site, which allows one to enter a location and an eclipse date, and see what the specific times for and appearance of a solar eclipse. The tool includes a map that users can click on to specify a location. Jubier’s main site also includes images and maps from numerous eclipse expeditions and upcoming eclipses.
Solar Eclipse Eye Safety / American Academy of Opthalmology
https://www.aao.org/eye-health/tips-prevention/solar-eclipse-eye-safety
A short article based on information provided by the American Astronomical Society, this piece presents tips on safely viewing eclipses.
Total Solar Eclipse August 21, 2017 / NASA
https://eclipse2017.nasa.gov/
This site, though created specifically for the 2017 eclipse, includes a variety of information on eclipses in general as well as images, videos, apps and other material available for viewing and downloading. An education page includes links to activities for students of all ages and a citizen science page lists several scientific projects that took place during the eclipse, as well as some that are going. Other resources on the page include links to relevant information from other agencies and even a page on eclipses and music.
USNO Eclipse Portal
http://astro.ukho.gov.uk/eclbin/query_usno.cgi
The United States Naval Observatory’s U.S. Nautical Almanac Office and Her Majesty's Nautical Almanac Office of the United Kingdom jointly produce an Astronomical Almanac. The data from that project is used to create maps and simple animations that show what an eclipse should look like from different major cities. Eclipses from the year 1501 to the year 2100 are included. The USNO Eclipse portal itself can only be searched by year, but a list of locations is available. Each of the included locations has a list of eclipses visible from that site. The USNO also has a page specifically for the 2017 eclipse.
