Fred Espenak

Introduction


The Annular Solar Eclipse of 2042 Oct 14 is visible from the following geographic regions:

  • Partial Eclipse: southeast Asia, East Indies, Australia, south Pacific, Antarctica
  • Annular Eclipse: Thailand, Malaysia, Indonesia, Australia, New Zealand

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 2042 Oct 14 at 02:00:42 TD (01:59:21 UT1). This is 0.3 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 1482.

The eclipse belongs to Saros 144 and is number 18 of 70 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.

The solar eclipse of 2042 Oct 14 is a relatively long annular eclipse with a duration at greatest eclipse of 07m44s. It has an eclipse magnitude of 0.9301.

The annular solar eclipse of 2042 Oct 14 is preceded two weeks earlier by a penumbral lunar eclipse on 2042 Sep 29.

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 80.7 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 = 2.000

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 2042 Oct 14 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 80.7 seconds for this eclipse.
