Introduction


The Total Lunar Eclipse of 2083 Jul 29 is visible from the following geographic regions:

  • Americas, Europe, Africa, western Asia, western Australia

The diagram to the right depicts the Moon's path with respect to Earth's umbral and penumbral shadows. Below it is a map showing the geographic regions of eclipse visibility.

The instant of greatest eclipse takes place on 2083 Jul 29 at 01:05:34 TD (01:03:43 UT1). This is 2.8 days after the Moon reaches perigee. During the eclipse, the Moon is in the constellation Capricornus. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1986.

The eclipse belongs to Saros 130 and is number 38 of 71 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.

This total eclipse is central meaning the Moon’s disk actually passes through the axis of Earth’s umbral shadow. It has an umbral eclipse magnitude of 1.4773, and Gamma has a value of -0.2143. Because they are so deep, such eclipses typically have the longest total phases. In this case, the duration of totality lasts 90.4 minutes.

The total lunar eclipse of 2083 Jul 29 is preceded two weeks earlier by a partial solar eclipse on 2083 Jul 15, and it is followed two weeks later by a partial solar eclipse on 2083 Aug 13.

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., TD = UT1 + ΔT). ΔT has a value of 111.1 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 = 1.000

Eclipse Predictions

Predictions for the Total Lunar Eclipse of 2083 Jul 29 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.
