Introduction


The Annular Solar Eclipse of 1907 Jul 10 is visible from the following geographic regions:

  • Partial Eclipse: South America, Central America, Antarctica
  • Annular Eclipse: Chile, Bolivia, Brazil

The instant of greatest eclipse takes place on 1907 Jul 10 at 15:24:32 TD (15:24:25 UT1). This is 0.7 days after the Moon reaches apogee. During the eclipse, the Sun is in the constellation Gemini. The synodic month in which the eclipse takes place has a Brown Lunation Number of -191.

The eclipse belongs to Saros 125 and is number 48 of 73 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 solar eclipse of 1907 Jul 10 is a relatively long annular eclipse with a duration at greatest eclipse of 07m23s. It has an eclipse magnitude of 0.9456.

The annular solar eclipse of 1907 Jul 10 is followed two weeks later by a partial lunar eclipse on 1907 Jul 25.

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 6.9 seconds for this eclipse.

The following links provide maps and data for the eclipse.

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 1907 Jul 10 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 6.9 seconds for this eclipse.
