Introduction

The Partial Solar Eclipse of 1917 Jun 19 is visible from the following geographic regions:

• Partial Eclipse: north North America, north Asia, north Europe

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 1917 Jun 19 at 13:16:20 TD (13:16:01 UT1). This is 5.1 days before the Moon reaches apogee. 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 -68.

The eclipse belongs to Saros 116 and is number 67 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.

This is a very deep partial eclipse. It has an eclipse magnitude of 0.4730, while Gamma has a value of 1.2857.

The partial solar eclipse of 1917 Jun 19 is followed two weeks later by a total lunar eclipse on 1917 Jul 04.

Another solar eclipse occurs one synodic month after the 1917 Jun 19 eclipse. It is the partial solar eclipse of 1917 Jul 19.

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 19.6 seconds for this eclipse.

Polynomial Besselian Elements: Partial Solar Eclipse of 1917 Jun 19

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 Partial Solar Eclipse of 1917 Jun 19 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 19.6 seconds for this eclipse.
