Catalog of Lunar Eclipse Saros Series

Saros Series 164

The periodicity and recurrence of lunar (and solar) eclipses is governed by the Saros cycle, a period of approximately 6,585.3 days (18 years 11 days 8 hours). When two eclipses are separated by a period of one Saros, they share a very similar geometry. The two eclipses occur at the same node[1] with the Moon at nearly the same distance from Earth and at the same time of year. Thus, the Saros is useful for organizing eclipses into families or series. Each series typically lasts 12 to 15 centuries and contains 70 or more lunar eclipses.

Lunar eclipses of Saros 164 all occur at the Moon’s ascending node and the Moon moves southward with each eclipse. The series will begin with a penumbral eclipse near the northern edge of the penumbra on 2400 Aug 05. The series will end with a penumbral eclipse near the southern edge of the penumbra on 3662 Sep 11. The total duration of Saros series 164 is 1262.11 years. In summary:

First Eclipse = 2400 Aug 05 12:01:19 TD Last Eclipse = 3662 Sep 11 16:35:05 TD

Duration of Saros 164 = 1262.11 Years

Saros 164 is composed of 71 lunar eclipses as follows:

                                 **7  Penumbral**

The longest and shortest eclipses of Saros 164 are as follows.

Longest Total Lunar Eclipse: 3013 Aug 13 Duration = 01h39m51s Shortest Total Lunar Eclipse: 2905 Jun 08 Duration = 00h06m28s

Longest Partial Lunar Eclipse: 3229 Dec 22 Duration = 03h05m05s Shortest Partial Lunar Eclipse: 2580 Nov 22 Duration = 00h49m07s

Longest Penumbral Lunar Eclipse: 2562 Nov 12 Duration = 04h32m32s Shortest Penumbral Lunar Eclipse: 2400 Aug 05 Duration = 01h22m48s

The largest and smallest magnitude partial eclipses of Saros 164 are:

Largest Partial Lunar Eclipse: 3229 Dec 22 Magnitude = 0.9806 Smallest Partial Lunar Eclipse: 2580 Nov 22 Magnitude = 0.0442

Local circumstances at greatest eclipse[2] for every lunar eclipse of Saros 164 are presented in the following catalog. For eclipses occurring between the years -1999 to +3000 (2000 BCE to 3000 CE), the sequence number in the first column links to a eclipse geometry diagram and a map from Five Millennium Canon of Lunar Eclipses: -1999 to +3000. A detailed key and additional information about the catalog can be found at: Key to Catalog of Lunar Eclipse Saros Series.

Footnotes

[1] The Moon's orbit is inclined about 5 degrees to Earth's orbit around the Sun. The points where the lunar orbit intersects the plane of Earth's orbit 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]Greatest eclipse is defined as the instant when Moon passes closest to the axis of Earth's shadow.

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:

pre-1950's: ΔT calculated from empirical fits to historical records derived by Morrison and Stephenson (2004)
1955-present: ΔT obtained from published observations
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.
