Description

The Thousand Year Canon of Lunar Eclipses 1501 to 2500 contains diagrams, maps and data for each of the 2,424 lunar eclipses occurring over the ten century period centered on the present era. The eclipse predictions are based on the Jet Propulsion Lab's DE406 - a computer ephemeris used for calculating high precision coordinates of the Sun and Moon for thousands of years into the past and future.

Section 1 of the Canon presents fundamental concepts including eclipse classification and the visual appearance of each type of eclipse. Section 2 discusses the eclipse predictions, the constants used and Delta T. A statistical analysis of eclipse frequency, extremes in eclipse magnitude, greatest duration and quincena combinations are covered in Section 3. 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 information presented in each of the lunar eclipse figures (Appendix B).

The primary content of the Thousand Year Canon resides in the two 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, eclipse magnitude, geographic coordinates of greatest eclipse, Sun's altitude and azimuth, central path width and central line duration (Click here to see a sample page of the catalog).

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 2,424 figures are arranged twelve to a page at an image scale permitting the assessment of eclipse visibility from any location on Earth. 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 (Click here to see a sample page of figures & maps).

Note that there is also a Color Edition of the Thousand Year Canon of Lunar Eclipses that features color diagrams of every lunar eclipse.

The maps and data presented in the Thousand Year Canon of Lunar Eclipses form the basis of the eclipse prediction website EclipseWise.com. The complementary publication, Thousand Year Canon of Solar Eclipses 1501 to 2500, contains diagrams, maps and data for all 2,389 eclipses of the Sun occurring over the same time period.
