Introduction


The Partial Solar Eclipse of 1928 Jun 17 is visible from the following geographic regions:

  • Partial Eclipse: Russia

The instant of greatest eclipse takes place on 1928 Jun 17 at 20:27:28 TD (20:27:04 UT1). This is 1.3 days after the Moon reaches perigee. 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 155 and is number 1 of 71 eclipses in the series. Thus, the 1928 Jun 17 event is the very first eclipse of 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.

This is an extremely shallow partial eclipse. It has an eclipse magnitude of only 0.0376, while Gamma has a value of 1.5107. This is a very deep partial eclipse. It has an eclipse magnitude of 0.0376, while Gamma has a value of 1.5107.

The partial solar eclipse of 1928 Jun 17 is preceded two weeks earlier by a total lunar eclipse on 1928 Jun 03.

Another solar eclipse occurs one synodic month before the 1928 Jun 17 eclipse. It is the total solar eclipse of 1928 May 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 24.2 seconds for this 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 Partial Solar Eclipse of 1928 Jun 17 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 24.2 seconds for this eclipse.
