Introduction


The Total Solar Eclipse of 1919 May 29 is visible from the following geographic regions:

  • Partial Eclipse: South America, Central America, Africa
  • Total Eclipse: Chile, Peru, Bolivia, Brazil, central Africa

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 1919 May 29 at 13:08:55 TD (13:08:34 UT1). This is 0.8 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Taurus. The synodic month in which the eclipse takes place has a Brown Lunation Number of -44.

The eclipse belongs to Saros 136 and is number 32 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.

The solar eclipse of 1919 May 29 is an exceptionally long total eclipse with a duration at greatest eclipse of 06m51s. It has an eclipse magnitude of 1.0719.

The total solar eclipse of 1919 May 29 is preceded two weeks earlier by a penumbral lunar eclipse on 1919 May 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 21.0 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 = 13.000

Eclipse Predictions

Predictions for the Total Solar Eclipse of 1919 May 29 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 21.0 seconds for this eclipse.
