Introduction


The Annular Solar Eclipse of 1922 Mar 28 is visible from the following geographic regions:

  • Partial Eclipse: east South America, Carribean, north Africa, Europe, west Asia
  • Annular Eclipse: Peru, Brazil, Senegal, Mali, Mauritania, Algeria, Libya, Egypt, Saudi Arabia

The instant of greatest eclipse takes place on 1922 Mar 28 at 13:05:26 TD (13:05:03 UT1). This is 2.7 days after the Moon reaches apogee. During the eclipse, the Sun is in the constellation Pisces. The synodic month in which the eclipse takes place has a Brown Lunation Number of -9.

The eclipse belongs to Saros 128 and is number 53 of 73 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 1922 Mar 28 is a relatively long annular eclipse with a duration at greatest eclipse of 07m50s. It has an eclipse magnitude of 0.9381.

The annular solar eclipse of 1922 Mar 28 is preceded two weeks earlier by a penumbral lunar eclipse on 1922 Mar 13, and it is followed two weeks later by a penumbral lunar eclipse on 1922 Apr 11.

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 22.7 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 = 13.000

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 1922 Mar 28 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 22.7 seconds for this eclipse.
