Description

The 21st Century Canon of Lunar Eclipses contains maps and data for all 228 lunar eclipses occurring during the 100-year period from 2001 through 2100. The eclipse predictions are based on the Jet Propulsion Lab's DE431 - a computer ephemeris used for calculating high precision coordinates of the Sun and Moon for hundreds of years into the past and future. The predictions also use a new elliptical model for Earth's shadows, which is the most rigorous and accurate method to date. Read all about this new elliptical shadow model as described in the 21st Century Canon,

Visit the following link to see the Table of Contents.

Section 1 of the Canon presents basic fundamentals including eclipse classification, the visual appearance of each type of eclipse, and the Danjon Scale of eclipse brightness. Section 2 discusses the eclipse predictions, the major contact definitions, the enlargement of Earth's shadows, coordinates of the Sun and Moon, and Delta T. Section 3 looks at the frequency of lunar eclipses, extremes in penumbral and umbral eclipse magnitudes, durations of penumbral, partial and total eclipses, and eclipse seasons. A concise explanation of the data contained in the lunar eclipse catalog (Appendix A) appears in Section 4 while Section 5 offers a complete description of the diagrams and maps presented for each lunar eclipse in Appendices B and C.

The primary content of the 21st Century Canon of Lunar Eclipses resides in the three 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 number, gamma, penumbral and umbral eclipse magnitudes, durations of the penumbral, partial and total phases, and the geographic location where the Moon appears at the zenith at greatest eclipse.

Appendix B is an atlas of figures depicting the path of the Moon through Earth's shadows and maps identifying the geographic regions of visibility of each eclipse. The 228 figures are arranged twelve to a page. Other data on each figure include the eclipse type, calendar date and time of greatest eclipse, Saros series number, lunar node, Delta T, gamma, eclipse magnitudes, and phase durations.

Appendix C zeros in on the lunar eclipses with a detailed full-page path diagrams and maps of each eclipse.

Appendix C contains zeros in on individual lunar eclipses with a detailed full-page path diagrams and maps of each eclipse.

The 21st Century Canon of Lunar Eclipses is available in two editions: 1) Standard Edition and 2) Deluxe Edition.
And each of them is available in either Black & White or Full Color.

The only difference between the two editions is in Appendix C.

In the Standard Edition, Appendix C contains 112 full-page diagrams and maps - one for each lunar eclipse from 2021 through 2070.
In comparison, Appendix C in the Deluxe Edition contains 228 full-page diagrams and maps - one for each lunar eclipse from 2001 through 2100.

Below is the key to the full-page diagrams and maps in Appendix C. It identifies the various features in each.

The 21st Century Canon of Lunar Eclipses is the modern successor to the NASA publication Fifty Year Canon of Lunar Eclipses. The 21st Century Canon is far more precise and includes details on the face of the Moon. It uses modern and more accurate ephemerides for the Sun and Moon (JPL DE430). It also uses an improved parameters and an elliptical model for Earth's shadows. Compare the diagrams and maps of the 2022 total eclipse from the two canons above to see the improvement.

Eclipse Almanac

The Eclipse Almanac is a series of five publications. Each one is a concise reference for every eclipse of the Sun and the Moon over a 10-year period. This compendium identifies when and where each of these events will be seen. Particular details about each eclipse are included, as well as a 25-year table looking further into the future.

Section 1 presents solar eclipses including an explanation of why they occur, types of solar eclipses, and the visual appearance of each. Global maps depict the geographic regions of visibility of each of the 22 to 23 solar eclipses.

Section 2 covers lunar eclipses explaning why they occur, the types of lunar eclipses, and the appearance of each. Detailed figures illustrate each of the 22 to 23 lunar eclipses including the Moon's path through Earth's shadows, and a map of the geographic visibility of every eclipse.

Section 3 lists the date and time of the Moon’s phases over the decade.

The five volume Eclipse Almanac series covers the decades from 2021 to 2070.

21st Century Canon of Solar Eclipses

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 the fundamentals about solar eclipses. Section 2 discusses the eclipse the predictions, the constants used. 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.

The primary content of the "21st Century Canon" resides in the four appendices. Appendix A is a comprehensive catalog of solar eclipses. Appendix B is an atlas of maps (12 per page) depicting the geographic regions of visibility of each eclipse. Appendix C zeros in on full-page maps each solar eclipse. Curves of Maximum Time and Curves of 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.
