NASA Catalog of Lunar Eclipses in Saros 140 (original) (raw)

Catalog of Lunar Eclipse Saros Series

Saros Series 140

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 140 all occur at the Moon’s ascending node and the Moon moves southward with each eclipse. The series began with a penumbral eclipse near the northern edge of the penumbra on 1597 Sep 25. The series will end with a penumbral eclipse near the southern edge of the penumbra on 2968 Jan 06. The total duration of Saros series 140 is 1370.29 years. In summary:

First Eclipse = 1597 Sep 25 13:40:53 TD Last Eclipse = 2968 Jan 06 21:40:03 TD

Duration of Saros 140 = 1370.29 Years

Saros 140 is composed of 77 lunar eclipses as follows:

The longest and shortest eclipses of Saros 140 are as follows.

Longest Total Lunar Eclipse: 2264 Nov 04 Duration = 01h38m36s Shortest Total Lunar Eclipse: 2102 Jul 30 Duration = 00h31m19s

Longest Partial Lunar Eclipse: 2607 Jun 02 Duration = 03h13m02s Shortest Partial Lunar Eclipse: 1958 May 03 Duration = 00h21m02s

Longest Penumbral Lunar Eclipse: 2733 Aug 17 Duration = 04h20m49s Shortest Penumbral Lunar Eclipse: 2968 Jan 06 Duration = 00h36m57s

The largest and smallest magnitude partial eclipses of Saros 140 are:

Largest Partial Lunar Eclipse: 2607 Jun 02 Magnitude = 0.9923 Smallest Partial Lunar Eclipse: 1958 May 03 Magnitude = 0.0092

Local circumstances at greatest eclipse[2] for every lunar eclipse of Saros 140 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:

  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.
