Total Solar Eclipse of 2043 Apr 09

Introduction


The Total Solar Eclipse of 2043 Apr 09 is visible from the following geographic regions:

  • Partial Eclipse: north North America, northeast Asia
  • Total Eclipse: northeast Russia

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 Apr 09 at 18:57:49 TD (18:56:28 UT1). This is 0.9 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Aries. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1488.

The eclipse belongs to Saros 149 and is number 22 of 71 eclipses in the series. All eclipses in this series occur at the Moon’s ascending node. The Moon moves southward with respect to the node with each succeeding eclipse in the series and gamma decreases.

This total eclipse is very unusual in that it is NON-CENTRAL and does NOT have a central line nor a northern path limit. Instead , over half of the umbral shadow falls off into space throughout the eclipse. Gamma has a value of 1.0031.

The total solar eclipse of 2043 Apr 09 is preceded two weeks earlier by a total lunar eclipse on 2043 Mar 25.

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 81.0 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 = 19.000

Eclipse Predictions

Predictions for the Total Solar Eclipse of 2043 Apr 09 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 81.0 seconds for this eclipse.
