Five Millennium Catalog of Solar Eclipses

-1999 to +3000 (2000 BCE to 3000 CE)

Introduction

Eclipses of the Sun can only occur when the Moon is near one of its two orbital nodes [1] during the New Moon phase . 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. [2]

Total eclipses are visible from within the Moon's umbral shadow while annular eclipses are seen within the antumbral shadow . These eclipses can be classified as central [3] or non-central 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.

The recurrence of solar eclipses is governed by the Saros cycle. For more information, see Periodicity of Solar Eclipses.

Statistics for Solar Eclipses: -1999 to +3000 (2000 BCE to 3000 CE)

During the five Millennium period -1999 to +3000 (2000 BCE to 3000 CE[4]), Earth will experience 11898 solar eclipses. The following table shows the number of eclipses of each type over this period.

Solar Eclipses: -1999 to +3000
Eclipse Type	Symbol	Number	Percent
All Eclipses	-	11898	100.0%
Partial	P	4200	35.3%
Annular	A	3956	33.2%
Total	T	3173	26.7%
Hybrid	H	569	4.8%

Annular and total eclipses can be further classified as either: 1) Central (two limits), 2) Central (one limit) or 3) Non-Central (one limit). 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).

Annular and Total Eclipses (Combined)
Classification	Number	Percent
All	7129	100.0%
Central (two limits)	6948	97.5%
Central (one limit)	87	1.2%
Non-Central (one limit)	94	1.3%

Annular Eclipses
Classification	Number	Percent
All Annular Eclipses	3956	100.0%
Central (two limits)	3827	96.7%
Central (one limit)	61	1.5%
Non-Central (one limit)	68	1.7%

Total Eclipses
Classification	Number	Percent
All Total Eclipses	3173	100.0%
Central (two limits)	3121	98.4%
Central (one limit)	26	0.8%
Non-Central (one limit)	26	0.8%

There are a minimum of two and a maximum of five solar eclipses in every calendar year. Statistics for the number of eclipses each year over the 5000 year period are listed below.

Five Millennium Catalog of Solar Eclipses: -1999 to +3000 (2000 BCE to 3000 CE)

The table below summarizes all eclipses over this five millennium period by century. 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[5], 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.

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. 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 ). 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. 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).

The largest uncertainty in the eclipse predictions is caused by fluctuations in Earth's rotation due primarily to tidal friction of the Moon. The resultant drift in apparent clock time is expressed as ΔT 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 have been derived to simplify the evaluation of ΔT for any time from -1999 to +3000. The uncertainty in ΔT over this period can be estimated from scatter in the measurements.

Footnotes

[1] The Moon's orbit is inclined about 5.1° to Earth's orbit around the Sun (i.e., the ecliptic). The two points where the orbits intersect are known as the nodes. The Moon moves from south to north of Earth's orbit at the ascending node, and from north to south at the descending node.

[2] Hybrid eclipses are also known as annular/total eclipses. Such an eclipse is both total and annular along different sections of its umbral path. (See: Five Millennium Catalog of Hybrid Solar Eclipses)

[3] Central solar eclipses are eclipses in which the central axis of the Moon's shadow strikes the Earth's surface. All partial (penumbral) eclipses are non-central eclipses since the shadow axis misses Earth. However, umbral eclipses (total, annular and hybrid) may be either central (usually) or non-central (rarely).

[4] 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 )

[5] Greatest eclipse is defined as the instant when the axis of the Moon's shadow passes closest to the 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.

[6] The first quantity is the number of central eclipses, while the second quantity [in square brackets] is the number of non-central eclipses.
