Introduction

The Total Solar Eclipse of 1966 Nov 12 is visible from the following geographic regions:

Partial Eclipse: Central America, South America, south Africa
Total Eclipse: Peru, Chile, Bolivia, Argentina, Uruguay, Brazil

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 1966 Nov 12 at 14:23:28 TD (14:22:50 UT1). This is 2.2 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Libra. The synodic month in which the eclipse takes place has a Brown Lunation Number of 543.

The eclipse belongs to Saros 142 and is number 20 of 72 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 total solar eclipse of 1966 Nov 12 is preceded two weeks earlier by a penumbral lunar eclipse on 1966 Oct 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 37.3 seconds for this eclipse.

Eclipse Predictions

Predictions for the Total Solar Eclipse of 1966 Nov 12 were generated using the JPL DE405 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 37.3 seconds for this eclipse.
