Introduction

The Partial Solar Eclipse of 2083 Aug 13 is visible from the following geographic regions:

  • Partial Eclipse: South America, Antarctica

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 2083 Aug 13 at 12:34:41 TD (12:32:50 UT1). This is 6.4 days after the Moon reaches apogee. During the eclipse, the Sun is in the constellation Leo. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1987.

The eclipse belongs to Saros 156 and is number 5 of 69 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 0.6146, while Gamma has a value of -1.2064.

The partial solar eclipse of 2083 Aug 13 is preceded two weeks earlier by a total lunar eclipse on 2083 Jul 29.

Another solar eclipse occurs one synodic month before the 2083 Aug 13 eclipse. It is the partial solar eclipse of 2083 Jul 15.

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 111.1 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 = 13.000

Eclipse Predictions

Predictions for the Partial Solar Eclipse of 2083 Aug 13 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 111.1 seconds for this eclipse.
