Introduction

The Six Millennium Catalog of Lunar Eclipses is organized into a series of sixty 100-year web pages, each one covering a century of lunar eclipses. The 100-year table below covers the period -2899 to -2800 (2900 BCE to 2801 BCE) [1]. The date and time of each eclipse is given for the instant of Greatest Eclipse [2]. Each eclipse date links to a web page containing additional details and a map showing the geographic region of eclipse visibility for that eclipse. A description of each parameter in the catalog table can be found in Key to Catalog of Lunar Eclipses.

For an explanation of how eclipses are classified, see Lunar Eclipse Basics. The frequency of each eclipse type, the extremes in eclipse magnitude and duration, and other data for the century are presented in the Eclipse Statistics tables following the Catalog of Lunar Eclipses. To select a different century, visit the Index to Six Millennium Catalog of Lunar Eclipses.

Statistics for Lunar Eclipses: -2899 to -2800 (2900 BCE to 2801 BCE)

During the 29th century BCE [1], Earth experienced 231 lunar eclipses. The following table shows the number of eclipses of each type over this period.

Lunar Eclipses: -2899 - -2800
Eclipse Type	Symbol	Number	Percent
All Eclipses	-	231	100.0%
Penumbral	N	84	36.4%
Partial	P	69	29.9%
Total	T	78	33.8%

Total eclipses can be further classified as either central or non-central:

• Central - Some portion of the Moon passes directly through the center of Earth’s umbral shadow.
  These are the deepest and longest type of lunar eclipse.
• Non-Central - The Moon passes completely within Earth’s umbral shadow but misses the center of the umbra.

The statistical distribution of these classes during the 29th century BCE appears in the following table.

Total Eclipses
Classification	Number	Percent
All	78	100.0%
Central	33	42.3%
Non-Central	45	57.7%

There are two to five lunar eclipses in every calendar year. Statistics for the number of eclipses each year during the century are listed below.

When four consecutive lunar eclipses are all total eclipses, the series is known as a tetrad. The following table lists the dates of all total eclipses in the 6 tetrads occurring during this century.

Lunar Eclipse Tetrad Series

1	-2898 Apr 09	-2898 Oct 02	-2897 Mar 29	-2897 Sep 21
2	-2880 Apr 19	-2880 Oct 12	-2879 Apr 08	-2879 Oct 02
3	-2851 Mar 30	-2851 Sep 23	-2850 Mar 19	-2850 Sep 12
4	-2840 Feb 27	-2840 Aug 22	-2839 Feb 15	-2839 Aug 12
5	-2822 Mar 09	-2822 Sep 03	-2821 Feb 27	-2821 Aug 23
6	-2804 Mar 20	-2804 Sep 13	-2803 Mar 09	-2803 Sep 02

During the century, 1 Saros series begin and 4 Saros series end. The table below gives the Saros series, number of eclipses in the series, the calendar date and whether it is the first or last eclipse in the series.

First or Last Eclipse in Saros Series
Saros Series	Number of Eclipses	Date	Pernumbral Magnitude	First/Last
-47	75	-2896 Aug 12	0.0348	Last
-45	74	-2874 Jun 10	0.0676	Last
-51	90	-2867 Jan 26	0.0214	Last
-5	73	-2852 May 09	0.0306	First
-50	88	-2802 Jan 28	0.0387	Last

There are two lunar eclipses in the same same calendar month as follows: -2827 Jun, -2816 May.

Footnotes

[1] 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)

[2] Greatest eclipse is defined as the instant when the center of the Moon passes closest to the axis of Earth's shadows.

Index to Six Millennium Catolog of Lunar Eclipses

The links in the following table each open a web page containing a 100-year Catalog of Lunar Eclipses. Each line in a 100-year catalog lists the primary characteristics for a single eclipse; the eclipse date itself links to a web page containing further details, an eclipse diagram and map showing the geographic region of eclipse visibility.

Calendar

The Gregorian calendar (also called the Western calendar) is internationally the most widely used civil calendar. It is named for Pope Gregory XIII, who introduced it in 1582. On this website, the Gregorian calendar is used for all calendar 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..

Eclipse Predictions

The eclipse predictions presented here were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates have been calculated with respect to the Moon's Center of Mass.

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 -2999 to +3000. The uncertainty in ΔT over this period can be estimated from scatter in the measurements.
