Description

The 21st Century Canon of Solar Eclipses contains maps and data for all 224 solar eclipses occurring during the 100-year period from 2001 through 2100. The eclipse predictions are based on the Jet Propulsion Lab's DE405 - a computer ephemeris used for calculating high precision coordinates of the Sun and Moon for hundreds of years into the past and future.

Section 1 of the Canon presents fundamental concepts including eclipse classification, the visual appearance of each type of eclipse, safe eclipse viewing tips, and how duration changes with distance from the central line. Section 2 discusses the eclipse the predictions, the constants used, time measurement and Delta T. A statistical analysis of eclipse frequency, extremes in eclipse magnitude, greatest central duration and quincena combinations are covered in Section 3. A concise explanation of the data contained in the solar eclipse catalog (Appendix A) and detailed descriptions of the solar eclipse maps (Appendices B, C and D) appear in Sections 4 and 5.

The primary content of the 21st Century Canon of Solar Eclipses resides in the four appendices. Appendix A is a comprehensive catalog listing the essential characteristics of each eclipse. These include the calendar date and time of greatest eclipse, Delta T, lunation number, Saros series, gamma, eclipse magnitude, geographic coordinates of greatest eclipse, Sun's altitude and azimuth, central path width and central line duration. Appendix B is an atlas of maps depicting the geographic regions of visibility of each eclipse. The zones of partial and central eclipse are plotted using an orthographic (global) map projection. The 224 maps are arranged twelve to a page permitting the assessment of eclipse visibility from any location on Earth.

The following three images are sample pages from Appendices B, C and D. Click on each to open a full-size, full-resolution sample.

Appendix C contains zeros in on every solar eclipses from 2017 through 2066 with a detailed full page map of each. Curves of Time of Maximum Eclipse and Curves of Constant Eclipse Magnitude permit the estimation of time and magnitude from any geographic location. Finally, Appendix D plots the track of every central eclipse (total, annular and hybrid) on large scale maps to allow the identification of countries and major cities within each eclipse path.

The 21st Century Canon of Solar Eclipses is available in three editions: 1) black & white, 2) color, and 3) deluxe.

The deluxe edition is similar to the color edition except that it has full page maps of all 224 solar eclipses during the 21st Century. This adds 110 pages to Appendix C, which increases the cost of the publication.

Below is the key to the large global eclipse maps in Appendix C. It identifies the various curves and features in each map.

The 21st Century Canon of Solar Eclipses is the modern successor to the NASA publication Fifty Year Canon of Solar Eclipses. But the 21st Century Canon is much more that just an update. It covers an entire century rather than only 50 years. The global maps in Appendix C are larger with more detail and include positions of hundreds of cities. Compare the global maps of the 2017 total eclipse from the two canons below to see the improvement in the new canon.

Atlas of Central Solar Eclipses in the USA

The Atlas of Central Solar Eclipses in the USA contains of a series of 499 global maps showing the geographic track of every total and annular solar eclipse across the USA (including Alaska and Hawaii) during the two-thousand-year period 1001 through 3000. It is accompanied by a catalog that lists the major characteristics of each eclipse including its duration and whether it is visible from the lower 48 states, Alaska and/or Hawaii.

A set of 20 detailed maps, each covering a 50-year period and centered on the lower 48 states, shows the path of every total and annular eclipse. The maps include state boundaries and major cities. These maps also cover southern Canada and northern Mexico.

Road Atlas of the Total Solar Eclipse of 2024

The Road Atlas for the Total Solar Eclipse of 2017 contains a comprehensive series of 26 maps of the path of totality across Mexico, the USA and Canada. The large scale (1 inch ≈ 22 miles) shows both major and minor roads, towns and cities, rivers, lakes, parks, national forests, wilderness areas and mountain ranges.

Although a partial eclipse will be seen from all of North America, the total phase in which the Moon completely covers the Sun (known as totality) will only be seen from within the 120-mile-wide path of the Moon’s umbral shadow as it sweeps across Mexico, the United States (Texas, Oklahoma, Arkansas, Missouri, Tennessee, Kentucky, Illinois, Indiana, Ohio, Michigan, Pennsylvania, New York, Vermont, New Hampshire, and Maine), and Canada (Ontario, Quebec, New Brunswick, Prince Edward Island, Nova Scotia and Newfoundland).

Armed with this atlas and the latest weather forecasts, the road warrior is ready to chase totality no matter where it takes him/her along the entire path. This mobile strategy offers the highest probability of witnessing the spectacular 2024 total eclipse in clear skies.

Totality - The Great American Eclipses of 2017 and 2024

The Totality - The Great American Eclipses of 2017 and 2024 is a complete guide to the most stunning of celestial sights, total eclipses of the Sun. It focuses on the eclipses of August 21, 2017 and April 8, 2024 that pass across the United States. The U.S. mainland has not experienced a total solar eclipse since 1979. This book provides information, photographs, and illustrations to help understand and safely enjoy all aspects of these eclipses including:

  • How to observe a total eclipse of the Sun
  • How to photograph and video record an eclipse
  • Why solar eclipses happen
  • The earliest attempts to understand and predict eclipses
  • The mythology and folklore of eclipses
  • The response of animals to total solar eclipses
  • The response of man to total eclipses through time
  • How scientists used total eclipses to understand how the Sun works
  • How astronomers used a total eclipse in 1919 to confirm Einstein's general theory of relativity
  • Weather prospects for the 2017 eclipse
  • Detailed maps of the path of totality for the 2017 eclipse and the eclipses of 2018 through 2024
  • Precise local times for the eclipses of 2017 and 2024 (the next total solar eclipse to visit the U.S.)
  • Color and black-and-white photographs, diagrams, and charts to illustrate and explain total solar eclipses
  • Global maps of total solar eclipses from 2017 to 2045 and lists of total and annual solar eclipses from 1970 through 2070
