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.

During the 5,000-year period from -1999 to +3000 (2000 BCE to 3000 CE), Earth will experience 11,898 eclipses of the Sun. The eclipses are distributed as follows: 4200 partial eclipses, 3956 annular eclipses, 3173 total eclipses, and 569 hybrid eclipses.The "Five Millennium Canon of Solar Eclipses" contains an individual global map for each eclipse delineating the geographic regions of visibility for both the partial and central (total, annular, or hybrid) phases. Modern political borders are plotted to assist in the determination of eclipse visibility. The uncertainty in Earth's rotational period expressed in delta T and its impact on the geographic visibility of eclipses in the past and future is discussed.The statistics of the solar eclipse distribution over 5,000 years are discussed in detail. This includes eclipse types by month and by century, eclipse frequency in the calendar year, extremes in eclipse magnitude for all eclipse types, maximum durations of total, annular, and hybrid eclipses, and eclipse duos (two eclipses within 30 days of each other).Finally, the periodicity of solar eclipses is investigated with particular attention to the Saros cycle. Tables list the start and end dates, number, and type of eclipses of every Saros series in progress during the 5,000-year period covered by the Five Millennium Canon.The "Five Millennium Canon of Solar Eclipses" comprises two volumes. Volume 1 covers eclipses for the years -1999 to 0, while volume 2 covers eclipses for the years 1 to 3000.
