It is then possible for the Moon's penumbral, umbral or antumbral shadows to sweep across Earth's surface thereby producing an eclipse. There are four types of solar eclipses: 1. *Partial* - Moon's penumbral shadow traverses Earth (umbral and antumbral shadows completely miss Earth) 2. *Annular* - Moon's antumbral shadow traverses Earth (Moon is too far from Earth to completely cover the Sun) 3. *Total* - Moon's umbral shadow traverses Earth (Moon is close enough to Earth to completely cover the Sun) 4. *Hybrid* - Moon's umbral and antumbral shadows traverse Earth (eclipse appears annular and total along different sections of its path). Hybrid eclipses are also known as annular-total eclipses. See Five Millennium Catalog of Hybrid Solar Eclipses <../SEcat5/SEhybrid5.html>. Annular eclipses are visible from within the Moon’s antumbral shadow while total eclipses are seen within the umbral shadow . These eclipses can be further classified as: 1. *Central (two limits)* - The central axis of the Moon’s shadow cone traverses Earth thereby producing a central line in the eclipse track. The umbra or antumbra falls entirely upon Earth so the ground track has both a northern and southern limit. 2. *Central (one limit)* - The central axis of the Moon’s shadow cone traverses Earth. However, a portion of the umbra or antumbra misses Earth throughout the eclipse and the resulting ground track has just one limit. 3. *Non-Central (one limit)* - The central axis of the Moon’s shadow cone misses Earth. However, one edge of the umbra or antumbra grazes Earth thereby producing a ground track with one limit and no central line. ------------------------------------------------------------------------ Solar Eclipses: -1999 to +3000 (2000 BCE to 3000 CE) During the five Millennium period -1999 to +3000 (2000 BCE to 3000 CE[1 <#1>]), Earth will experience 11898 solar eclipses. The following table shows the number of eclipses of each type over this period.

The statistical distribution of these classes over five millennia appears in the following three tables (no Hybrids are included since all are central with two limits).

Each line in the table gives a breakdown per century for each type of eclipse (partial, annular, total and hybrid). The date intervals themselves are each links to a catalog page listing full details for every solar eclipse in the corresponding century. The data in these 100 year eclipse tables include the date and time of greatest eclipse[2 <#2>], the eclipse type, Saros series, gamma, magnitude and local circumstances. For a detailed key and additional information about the catalogs, see: Key to Catalog of Solar Eclipses . Each of the 100 year tables is about 40 kilobytes in size. The data presented here are based on the /Five Millennium Canon of Solar Eclipses: -1999 to +3000 <../SEpubs/5MCSE.html>/. ------------------------------------------------------------------------ [1 <#1a>] The terms BCE and CE are abbreviations for "Before Common Era" and "Common Era," respectively. They are the secular equivalents to the BC and AD dating conventions. (See: Year Dating Conventions <../SEhelp/dates.html>) [2 <#2a>] Greatest eclipse is defined as the instant when the axis of the Moon's shadow cone passes closest to Earth's center. For total eclipses, the instant of greatest eclipse is virtually identical to the instants of greatest magnitude and greatest duration. However, for annular eclipses, the instant of greatest duration may occur at either the time of greatest eclipse or near the sunrise and sunset points of the eclipse path. ------------------------------------------------------------------------ Five Millennium Catalog of Solar Eclipses Century Interval Number of Eclipses Number of Partial Eclipses Number of Annular Eclipses[3 <#3>] Number of Total Eclipses[3 <#3>] Number of Hybrid Eclipses -1999 to -1900 239 84 70 [1] 62 [0] 22 -1899 to -1800 253 93 80 [0] 62 [1] 17 -1799 to -1700 254 95 73 [1] 63 [1] 21 -1699 to -1600 230 75 70 [1] 60 [0] 24 -1599 to -1500 225 78 65 [2] 59 [0] 21 -1499 to -1400 226 77 65 [4] 61 [1] 18 -1399 to -1300 234 76 83 [1] 68 [0] 6 -1299 to -1200 250 93 86 [0] 64 [0] 7 -1199 to -1100 252 93 89 [0] 63 [0] 7 -1099 to -1000 238 79 89 [2] 67 [1] 0 -0999 to -0900 226 84 74 [1] 58 [3] 6 -0899 to -0800 225 80 73 [2] 64 [2] 4 -0799 to -0700 234 79 88 [0] 64 [0] 3 -0699 to -0600 253 96 86 [1] 63 [0] 7 -0599 to -0500 255 96 85 [1] 65 [0] 8 -0499 to -0400 241 84 76 [2] 62 [0] 17 -0399 to -0300 225 83 62 [1] 56 [0] 23 -0299 to -0200 226 83 61 [1] 55 [2] 24 -0199 to -0100 237 80 71 [2] 62 [1] 21 -0099 to 0000 251 92 77 [0] 64 [1] 17 0001 to 0100 248 90 74 [1] 58 [0] 25 0101 to 0200 237 80 75 [2] 63 [1] 16 0201 to 0300 227 79 70 [4] 69 [0] 5 0301 to 0400 222 73 74 [2] 65 [1] 7 0401 to 0500 233 80 83 [1] 67 [0] 2 0501 to 0600 251 93 86 [1] 65 [0] 6 0601 to 0700 251 90 89 [1] 67 [0] 4 0701 to 0800 233 77 86 [2] 66 [0] 2 0801 to 0900 222 78 72 [2] 62 [2] 6 0901 to 1000 227 76 83 [1] 65 [1] 1 1001 to 1100 241 84 90 [0] 61 [0] 6 1101 to 1200 250 92 82 [0] 61 [0] 15 1201 to 1300 246 87 80 [1] 60 [0] 18 1301 to 1400 229 76 72 [3] 54 [0] 24 1401 to 1500 222 77 62 [3] 60 [1] 19 1501 to 1600 228 75 69 [3] 62 [0] 19 1601 to 1700 248 89 74 [0] 60 [1] 24 1701 to 1800 251 92 78 [0] 62 [0] 19 1801 to 1900 242 87 77 [0] 63 [0] 15 1901 to 2000 228 78 71 [2] 68 [3] 6 2001 to 2100 224 77 70 [2] 67 [1] 7 2101 to 2200 235 79 82 [5] 65 [0] 4 2201 to 2300 248 92 86 [0] 67 [0] 3 2301 to 2400 248 88 86 [0] 66 [0] 8 2401 to 2500 237 81 87 [2] 65 [1] 1 2501 to 2600 225 83 71 [1] 63 [1] 6 2601 to 2700 227 77 78 [3] 64 [0] 5 2701 to 2800 242 84 92 [0] 63 [0] 3 2801 to 2900 254 95 86 [1] 63 [0] 9 2901 to 3000 248 91 80 [2] 64 [0] 11 [3 <#3a>]The first quantity is the number of central eclipses, while the second quantity [in square brackets] is the number of non-central eclipses. ------------------------------------------------------------------------ Calendar The Gregorian calendar is used for all dates from 1582 Oct 15 onwards. Before that date, the Julian calendar is used. For more information on this topic, see Calendar Dates <../SEhelp/calendar.html>. The Julian calendar does not include the year 0. Thus the year 1 BCE is followed by the year 1 CE (See: BCE/CE Dating Conventions <../SEhelp/dates.html> ). This is awkward for arithmetic calculations. Years in this catalog are numbered astronomically and include the year 0. Historians should note there is a difference of one year between astronomical dates and BCE dates. Thus, the astronomical year 0 corresponds to 1 BCE, and astronomical year -1 corresponds to 2 BCE, etc.. ------------------------------------------------------------------------ Predictions The coordinates of the Sun used in these predictions are based on the VSOP87 theory [Bretagnon and Francou, 1988]. The Moon's coordinates are based on the ELP-2000/82 theory [Chapront-Touze and Chapront, 1983]. For more information, see: Solar and Lunar Ephemerides <../SEcat5/ephemeris.html>. The revised value used for the Moon's secular acceleration <../SEcat5/secular.html> is n-dot = -25.858 arc-sec/cy*cy, as deduced from the Apollo lunar laser ranging experiment (Chapront, Chapront-Touze, and Francou, 2002). The largest uncertainty in the eclipse predictions is caused by fluctuations in Earth's rotation <../SEhelp/rotation.html> due primarily to tidal friction of the Moon. The resultant drift in apparent clock time is expressed as ΔT <../SEcat5/deltat.html> and is determined as follows: 1. pre-1950's: ΔT calculated from empirical fits to historical records derived by Morrison and Stephenson (2004) 2. 1955-present: ΔT obtained from published observations 3. future: ΔT is extrapolated from current values weighted by the long term trend from tidal effects A series of polynomial expressions <../SEcat5/deltatpoly.html> have been derived to simplify the evaluation of ΔT for any time from -1999 to +3000. The uncertainty in ΔT <../SEcat5/uncertainty.html> over this period can be estimated from scatter in the measurements. ------------------------------------------------------------------------ Acknowledgments Special thanks to *Jean Meeus* for providing the Besselian elements used in the solar eclipse predictions.
