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.

Eclipse Bulletin: Total Solar Eclipse of 2017 August 21

The Eclipse Bulletin: Total Solar Eclipse of 2017 August 21 is the complementary publication of the 2017 Road Atlas and is the ultimate guide to this highly anticipated event.

Local circumstances tables for more than 1000 cities across the USA provide times of each phase of the eclipse along with the eclipse magnitude, duration and Sun's altitude. Additional tables cover the eclipse circumstances for cities in Canada, Mexico, Central and South America and Europe. An exhaustive climatological study identifies areas along the eclipse path where the highest probability of favorable weather may be found. A travelogue highlights key locations in the eclipse track from Oregon through South Carolina.

Finally, comprehensive information is presented about solar filters and how to safely observe and photograph the eclipse.

Road Atlas for the Total Solar Eclipse of 2017

The Road Atlas for the Total Solar Eclipse of 2017 is a complementary publication of the 2017 Eclipse Bulletin. It contains a comprehensive series of 37 high resolution, full color maps of the path of totality across the USA.

The large scale (1:700,000 or 1 inch = 11 miles) shows both major and minor roads, towns and cities, rivers, lakes, parks, national forests, wilderness areas and mountain ranges.

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 2500-mile-long path. This mobile strategy offers the highest probability of witnessing the spectacular 2017 total eclipse in clear skies.

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.
