Introduction


The Annular Solar Eclipse of 1941 Mar 27 is visible from the following geographic regions:

  • Partial Eclipse: Antarctica, South America, Central America
  • Annular Eclipse: South Pacific, Peru, Bolivia, 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 1941 Mar 27 at 20:08:08 TD (20:07:43 UT1). This is 2.6 days before 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 226.

The eclipse belongs to Saros 138 and is number 27 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 1941 Mar 27 is a relatively long annular eclipse with a duration at greatest eclipse of 07m41s. It has an eclipse magnitude of 0.9355.

The annular solar eclipse of 1941 Mar 27 is preceded two weeks earlier by a partial lunar eclipse on 1941 Mar 13.

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 24.9 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 = 20.000

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 1941 Mar 27 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 24.9 seconds for this eclipse.
