Introduction


The Annular Solar Eclipse of 1962 Jul 31 is visible from the following geographic regions:

  • Partial Eclipse: northeast South America, southwest Europe, Africa
  • Annular Eclipse: Venezuela, Guyana, French Guyana, Senegal, Mali, Burkina Faso, Togo, Benin, Nigeria, Cameroon, Congo, Dem. Rep. Congo, Tanzania, Madagascar,

The instant of greatest eclipse takes place on 1962 Jul 31 at 12:25:33 TD (12:24:58 UT1). This is 4.7 days before the Moon reaches apogee. During the eclipse, the Sun is in the constellation Cancer. The synodic month in which the eclipse takes place has a Brown Lunation Number of 490.

The eclipse belongs to Saros 135 and is number 36 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.

The annular solar eclipse of 1962 Jul 31 is preceded two weeks earlier by a penumbral lunar eclipse on 1962 Jul 17, and it is followed two weeks later by a penumbral lunar eclipse on 1962 Aug 15.

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 34.3 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 = 12.000

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 1962 Jul 31 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 34.3 seconds for this eclipse.
