![]() The revised value used for the Moon's secular acceleration is n-dot = -25.858 arc-sec/cy*cy, as deduced from the Apollo lunar laser ranging experiment (Chapront, Chapront-Touze, and Francou, 2002). įor more information, see: Solar and Lunar Ephemerides. The Moon's coordinates are based on the ELP-2000/82 theory. The coordinates of the Sun used in the predictions are based on the VSOP87 theory. In this Catalog, Earth's penumbral and umbral shadow sizes have been calculated using Danjon's enlargement method. Lunar eclipse predictions must take into account the enlargement of Earth's shadows. Thus, the astronomical year 0 corresponds to 1 BCE, and astronomical year -1 corresponds to 2 BCE, etc. Historians should note there is a difference of one year between astronomical dates and BCE dates. Years in this catalog are numbered astronomically and include the year 0. This is awkward for arithmetic calculations. Thus the year 1 BCE is followed by the year 1 CE (See: BCE/CE Dating Conventions ). The Julian calendar does not include the year 0. The Gregorian calendar is used for all dates from 1582 Oct 15 onwards.īefore that date, the Julian calendar is used.įor more information on this topic, see Calendar Dates. The values in the square "" brackets are the number of central and non-central total eclipses, respectively. Total Eclipses: The first value is the number of all total eclipses (umbral). The values in the square "" brackets are the number of partial and total penumbral eclipses, respectively. Penumbral Eclipses: The first value is the number of all penumbral eclipses. Five Millennium Catalog of Lunar Eclipses ![]() Lunar libration number, Saros series, the eclipse type, quincena solar eclipse parameter, gamma, eclipse magnitudes, eclipse phase durations, and local circumstances.įor a detailed key and additional information about the catalogs, see: The data in these 100 year eclipse tables include the date and time of greatest eclipse, ΔT, The date intervals themselves are each a link to a catalog listing complete details for every lunar eclipse in the selected century. The table below summarizes the statistical distribution of lunar eclipse types over this five millennium period.Įach line in the table corresponds to one century and gives the breakdown of each eclipse type (penumbral, partial, and total). Longest Total Lunar Eclipse: 0318 May 31 Duration = 106.6mįive Millennium Catalog of Lunar Eclipses: -1999 to +3000 (2000 BCE to 3000 CE) ![]() Longest Partial Lunar Eclipse: 2669 Feb 08 Duration = 210.0m Longest Penumbral Lunar Eclipse: 1322 Nov 24 Duration = 296.5m The longest eclipses of the 5,000 year period are listed below. ![]() Statistics for the number of eclipses each year over the 5000 year period are listed below. There are a minimum of two and a maximum of five lunar eclipses in every calendar year. Using the above categories, the distribution of the 3,479 total eclipses is shown in the table below. Non-Central - The Moon misses the central axis of Earth's umbral shadow.Central - Some part of the Moon passes through the central axis of Earth's umbral shadow.Total lunar eclipses through Earth's umbral shadow can be categorized as: The table below shows the distribution of the two penumbral eclipse types during the 5000-year period of this Catalog. Such total penumbral eclipses are quite rare compared to normal (or partial) penumbral eclipses. Without entering the inner umbral shadow. However, it is also possible to have a penumbral eclipse in which the Moon passes completely within Earth's penumbral shadow Lunar Eclipses: -1999 to +3000ĭuring most penumbral eclipses, only part of the Moon passes through Earth's penumbral shadow. The following table shows the number of eclipses of each type over this period. Statistics for Lunar Eclipses: -1999 to +3000 (2000 BCE to 3000 CE)ĭuring the five Millennium period -1999 to +3000 (2000 BCE to 3000 CE), Earth will experience 12064 lunar eclipses. The recurrence of lunar eclipses is governed by the Saros cycle.įor more information, see Periodicity of Lunar Eclipses. The visual appearance of each of these eclipse types differs dramatically from each other. Total - Moon traverses Earth's penumbral and umbral shadows (Moon passes completely into Earth's umbra)įurthermore, total eclipses can be classified as either central or non-central.Partial - Moon traverses Earth's penumbral and umbral shadows (Moon does not pass completely into Earth's umbra).Penumbral - Moon traverses Earth's penumbral shadow (Moon misses Earth's umbral shadow).It is then possible for the Moon to pass through Earth's penumbral or umbral shadows thereby producing an eclipse. Index to Five Millennium Catalog of Lunar Eclipses -1999 to +3000 (2000 BCE to 3000 CE) IntroductionĮclipses of the Moon can occur when the Moon is near one of its two orbital nodes during the Full Moon phase.
