Annular Solar Eclipse of 2043 Oct 03

Introduction


The Annular Solar Eclipse of 2043 Oct 03 is visible from the following geographic regions:

  • Partial Eclipse: Antarctica, southwest Australia, Indian Ocean
  • Annular Eclipse: south Indian Ocean

The map to the right depicts the geographic regions of eclipse visibility. Click on the map to enlarge it. For an explanation of the features appearing in the map, see Key to Solar Eclipse Maps.

The instant of greatest eclipse takes place on 2043 Oct 03 at 03:01:49 TD (03:00:28 UT1). This is 4.8 days before the Moon reaches apogee. During the eclipse, the Sun is in the constellation Virgo. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1494.

The eclipse belongs to Saros 154 and is number 8 of 71 eclipses in the series. All eclipses in this series occur at the Moon’s descending node. The Moon moves northward with respect to the node with each succeeding eclipse in the series and gamma increases.

This annular eclipse is very unusual in that it is NON-CENTRAL and does NOT have a central line nor a southern path limit. Instead , over half of the antumbral shadow falls off into space throughout the eclipse. Gamma has a value of -1.0102.

The annular solar eclipse of 2043 Oct 03 is preceded two weeks earlier by a total lunar eclipse on 2043 Sep 19.

These eclipses all take place during a single eclipse season.

The eclipse predictions are given in both Terrestrial Dynamical Time (TD) and Universal Time (UT1). The parameter ΔT is used to convert between these two times (i.e., UT1 = TD - ΔT). ΔT has a value of 81.3 seconds for this eclipse.

The following links provide maps and data for the eclipse.

At time t1 (decimal hours), each besselian element is evaluated by:

x = x0 + x1*t + x2*t2 + x3*t3 (or x = Σ [xn*tn]; n = 0 to 3)

where: t = t1 - t0 (decimal hours) and t0 = 3.000

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 2043 Oct 03 were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass. The predictions are given in both Terrestrial Dynamical Time (TD) and Universal Time (UT1). The parameter ΔT is used to convert between these two times (i.e., UT1 = TD - ΔT). ΔT has a value of 81.3 seconds for this eclipse.
