The primary purpose of the "Fifty Year Canon of Solar Eclipses: 1986-2035" is to provide a reference of moderately detailed eclipse predictions and maps for use by the astronomical community. Such a work should be useful in identifying the most favorable eclipse opportunities, taking into account the celestial mechanics and geographic locations which are paramount in addressing the scientific goals, the issue of funding and the logistical problems of organizing an expedition to remove destinations. The secondary purpose is to provide a general reference on future eclipses for teachers, students, amateur astronomers and interested laymen. The solar eclipse is unquestionably the most spectacular celestial phenomenon visible to the naked eye. As such, eclipses generate a great deal of interest among the general public and news media. Naturally, questions arise as to where a particular eclipse will be visible from, and when the next eclipse occurs.

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" 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. Appendix C contains zeros in on the 224 solar eclipses with a detailed full page map of each. 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.

The 21st Century Canon of Lunar Eclipses - Black and White Edition contains diagrams, 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 Laboratory's DE430 - 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 21st Century 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 112 lunar eclipses from 2021 to 2070 with a detailed full-page path diagram and map of each eclipse. The 21st Century Canon of Lunar Eclipses is the expanded successor to the NASA publication Fifty Year Canon of Lunar Eclipses.
