Eclipse Predictions by Fred Espenak, NASA's GSFC Collected from: https://web.archive.org/web/20080311001653/http://sunearth.gsfc.nasa.gov/eclipse/SEcat5/catalog.html Key: https://web.archive.org/web/20070820134803/http://sunearth.gsfc.nasa.gov/eclipse/SEcat5/catkey.html Column Heading Definition/Description 1 Catalog Sequential number of the eclipse in the catalog links to Number the map published in the Five Millennium Canon of Solar Eclipses: -1999 to +3000. 2 Calendar Calendar Date at instant of Greatest Eclipse. Date Gregorian Calendar is used for dates after 1582 Oct 15. Julian Calendar is used for dates before 1582 Oct 04. 3 TD of Dynamical Time (TD) of Greatest Eclipse, the instant Greatest when the axis of the Moon's shadow cone passes closest Eclipse to Earth's center. 4 ΔT Delta T (ΔT) is the arithmetic difference between Dynamical Time and Universal Time. It is a measure of the accumulated clock error due to the variable rotation period of Earth. 5 Luna Lunation Number is the number of synodic months since Num New Moon of 2000 Jan 06. The Brown Lunation Number can be determined by adding 953. 6 Saros Saros series number of eclipse. Num (Each eclipse in a Saros is separated by an interval of 18 years 11.3 days.) 7 Ecl. Eclipse Type where: Type P = Partial Eclipse. A = Annular Eclipse. T = Total Eclipse. H = Hybrid or Annular/Total Eclipse. Second character in Eclipse Type: "m" = Middle eclipse of Saros series. "n" = Central eclipse with no northern limit. "s" = Central eclipse with no southern limit. "+" = Non-central eclipse with no northern limit. "-" = Non-central eclipse with no southern limit. "2" = Hybrid path begins total and ends annular. "3" = Hybrid path begins annular and ends total. "b" = Saros series begins (first eclipse in series). "e" = Saros series ends (last eclipse in series). 8 Gamma Distance of the shadow cone axis from the center of Earth (units of equatorial radii) at the instant of greatest eclipse. 9 Ecl. Eclipse magnitude is the fraction of the Sun's Mag. diameter obscured by the Moon. For annular, total and hybrid eclipses, this value is actually the diameter ratio of Moon/Sun. 10 Lat. Latitude where greatest eclipse is seen. 11 Long. Longitude where greatest eclipse is seen. 12 Sun Sun's altitude at greatest eclipse. Alt 13 Sun Sun's azimuth at greatest eclipse. Azm 14 Path Width of the path of totality or annularity Width at greatest eclipse (kilometers). 15 Central Central Line Duration of total or annular phase Dur. at greatest eclipse.
