NASA Catalog of Solar Eclipses of Saros 144 (original) (raw)

Saros Series 144

Introduction

The periodicity and recurrence of 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 13 centuries and contains 70 or more eclipses. Every saros series begins with a number of partial eclipses near one of Earth's polar regions. The series will then produce several dozen central[2] eclipses before ending with a group of partial eclipses near the opposite pole. For more information, see Periodicity of Solar Eclipses.

Statistics for Solar Eclipses of Saros 144

Solar eclipses of Saros 144 all occur at the Moon’s descending node and the Moon moves northward with each eclipse. The series began with a partial eclipse in the southern hemisphere on 1736 Apr 11. The series will end with a partial eclipse in the northern hemisphere on 2980 May 05. The total duration of Saros series 144 is 1244.08 years. In summary:

First Eclipse = 1736 Apr 11 07🔞07 TD Last Eclipse = 2980 May 05 22:48:34 TD

Duration of Saros 144 = 1244.08 Years

Saros 144 is composed of 70 solar eclipses as follows:

Umbral eclipses (annular, total and hybrid) 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 in Saros series 144 appears in the following table.

The following string illustrates the sequence of the 70 eclipses in Saros 144: 8P 39A 23P

The longest and shortest central eclipses of Saros 144 as well as largest and smallest partial eclipses are listed in the below.

Description of the Catalog of Solar Eclipses of Saros 144

The catalog below lists concise details and local circumstances at greatest eclipse[5] for every solar eclipse in Saros 144. A description or explanation of each parameter listed in the catalog can be found in Key to Catalog of Solar Eclipse Saros Series.

Several fields in the catalog link to web pages or files containing additional information for each eclipse (for the years -1999 through +3000). The following gives a brief explanation of each link.

• Catalog Number - link to a small global map showing geographic visibility of the eclipse
• Calendar Date - link to the path of central eclipse plotted on Google maps
• TD of Greatest Eclipse - link to a large global map showing geographic visibility of eclipse (years 1901 through 2100)
• Saros Num - link to a catalog of all eclipses in the Saros cycle
• Gamma - link to a table of Besselian elements for the eclipse
• Central Dur. - link to a table of coordinates of the central eclipse path (years 1901 through 2100)

For an animation showing how the eclipse path changes with each member of the series, see Animation of Saros 144.

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 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]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).

[3]Hybrid eclipses are also known as annular/total eclipses. Such an eclipse is both total and annular along different sections of its umbral path. For more information, see Five Millennium Catalog of Hybrid Solar Eclipses .

[4]Greatest eclipse is defined as the instant when the axis of the Moon's shadow passes closest to Earth's center. For total eclipses, the instant of greatest eclipse is nearly equal 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.
