Introduction


The Annular Solar Eclipse of 1915 Feb 14 is visible from the following geographic regions:

  • Partial Eclipse: Indies, Australia, Antarctica
  • Annular Eclipse: Australia, Indonesia, New Guinea

The instant of greatest eclipse takes place on 1915 Feb 14 at 04:33:20 TD (04:33:03 UT1). This is 6.6 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Capricornus. The synodic month in which the eclipse takes place has a Brown Lunation Number of -97.

The eclipse belongs to Saros 129 and is number 46 of 80 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 1915 Feb 14 is preceded two weeks earlier by a penumbral lunar eclipse on 1915 Jan 31, and it is followed two weeks later by a penumbral lunar eclipse on 1915 Mar 01.

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 17.3 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)

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 1915 Feb 14 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 17.3 seconds for this eclipse.
