In 2043, there are 2 solar eclipses and 2 lunar eclipses:

World maps show the regions of visibility for each eclipse. The lunar eclipse diagrams also include the path of the Moon through Earth’s shadow. Contact times for each principal phase are tabulated along with the magnitudes and geocentric coordinates of the Sun and the Moon at greatest eclipse.

Unless otherwise stated, all times and dates used in this publication are in Universal Time or UT1 [1]. This astronomically derived time system is colloquially referred to as Greenwich Mean Time or GMT. To learn more about UT1 and how to convert UT1 to your own local time, see Time Zones and Universal Time.

Total Lunar Eclipse of 2043 Mar 25

Under Construction

Diagram and map of the eclipse (Figure 1).

Table 1 lists predicted umbral immersion and emersion times for 25 well-defined lunar craters. The timing of craters is useful in determining the atmospheric enlargement of Earth's shadow (see Crater Timings During Lunar Eclipses).

This is the xx th eclipse of Saros [6] series 123

Complete details for the xx eclipses in the series may be found at Saros 123.

Eclipse Altitudes and Azimuths

The altitude a and azimuth A of the Sun or Moon during an eclipse depend on the time and the observer's geographic coordinates. They are calculated as follows: 

         h = 15 (GST + UT - α ) + λ
         a = arcsin [sin δ sin φ + cos δ cos h cos φ]
         A = arctan [-(cos δ sin h)/(sin δ cos φ - cos δ cos h sin φ)]

where

         h = hour angle of Sun or Moon
         a = altitude
         A = azimuth
         GST = Greenwich Sidereal Time at 0:00 UT
         UT = Universal Time
         α = right ascension of Sun or Moon
         δ = declination of Sun or Moon
         λ = observer's longitude (east +, west -)
         φ = observer's latitude (north +, south -)

During the eclipses of 2043 , the values for GST and the geocentric Right Ascension and Declination of the Sun or the Moon (at greatest eclipse) are as follows: 

                  Eclipse               Date             GST          α            δ

                  Total Lunar        2043 Mar 25   12.197   12.307   -1.616
                  Total Solar        2043 Apr 09   13.194    1.220    7.751
                  Total Lunar        2043 Sep 19   23.858   23.768   -1.859
                  Annular Solar        2043 Oct 03    0.781   12.601   -3.885

Two web based tools that can also be used to calculate the local circumstances for all solar and lunar eclipses visible from any location. They are the Javascript Solar Eclipse Explorer and the Javascript Lunar Eclipse Explorer. The URLs for these tools are:

Eclipse Web Sites

EclipseWise.com is a website dedicated to predictions and information on eclipses of the Sun and Moon. It offers a graphically intuitive interface and contains maps, diagrams, tables, and information about every solar and lunar eclipse from 2000 BCE to 3000 CE. This period includes 11898 solar eclipses and 12064 lunar eclipses.

Much of EclipseWise.com is based on the Thousand Year Canon of Solar Eclipses 1501 to 2500 (Espenak 2014a) and the Thousand Year Canon of Lunar Eclipses 1501 to 2500 (Espenak 2014b). These eclipse predictions use the Jet Propulsion Lab's DE406 — a computer ephemeris used for calculating high precision coordinates of the Sun and Moon for thousands of years into the past and future.

For eclipses over a larger time interval see Five Millennium Canon of Solar Eclipses –1999 to +3000 and Five Millennium Canon of Lunar Eclipses –-1999 to +3000.

The World Atlas of Solar Eclipses provides maps of all central eclipse paths from 2000 BCE to 3000 CE.

MrEclipse.com targets solar and lunar eclipse photography, with tips on eclipse observing and eye safety.

Acknowledgments

All eclipse predictions were generated on a Macintosh G4 PowerPC using algorithms developed from the Explanatory Supplement [1974] with additional algorithms from Meeus, Grosjean, and Vanderleen [1966]. The solar and lunar coordinates used in the eclipse predictions are based on the JPL DE405. For lunar eclipses, the elliptical shape of the umbral and penumbral shadows were calculated using Herald and Sinnott (2014) method of enlarging Earth's radius to compensate for the opacity of the terrestrial atmosphere (including corrections for the oblateness of Earth).

All calculations, diagrams, tables, and opinions presented in this paper are those of the author, and he assumes full responsibility for their accuracy.

Footnotes

[1] UT1 or Universal Time is the mean solar time on the Prime Meridian at Greenwich, England. Civil time signals are transmitted according to Coordinated Universal Time (UTC), which is based on International Atomic Time (TAI) with leap seconds added at irregular intervals to compensate for the slowing of Earth's rotation. The leap seconds keep UTC within 0.9 second of UT1.

[2] The instant of greatest eclipse for solar eclipses occurs when the distance between the Moon's shadow axis and Earth's geocenter reaches a minimum.

[3] Eclipse magnitude for solar eclipses is defined as the fraction of the Sun's diameter occulted by the Moon.

[4] Eclipse obscuration is defined as the fraction of the Sun's area occulted by the Moon.

[5] For solar eclipses, gamma is the distance of the Moon's shadow axis from Earth's center (in Earth radii) when it reaches its minimum absolute value.

[6] The Saros is a period of 6,585.3 days (18 years 11 days 8 hours) in which eclipses (both solar and lunar) repeat. The geometry isn't exact but close enough for a Saros series to last 12 or more centuries.

[7] The instant of greatest eclipse for lunar eclipses occurs when the distance between the Moon and Earth's shadow axis reaches a minimum.

[8] Umbral eclipse magnitude is defined as the fraction of the Moon's diameter occulted by Earth's umbral shadow.

[9] For lunar eclipses, gamma is the distance of the Moon's center from Earth's shadow axis (in Earth radii) when it reaches its minimum absolute value.

[10] Penumbral eclipse magnitude is defined as the fraction of the Moon's diameter occulted by Earth's penumbral shadow.
