Introduction

The Total Lunar Eclipse of 2069 Oct 30 is visible from the following geographic regions:

  • Americas, Europe, Africa, western Asia

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 2069 Oct 30 at 03:35:06 TD (03:33:26 UT1). This is 0.2 days before the Moon reaches perigee. During the eclipse, the Moon is in the constellation Aries. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1816.

The eclipse belongs to Saros 137 and is number 29 of 78 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 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 1.4628, and Gamma has a value of -0.2263. Because they are so deep, such eclipses typically have the longest total phases. In this case, the duration of totality lasts 87.4 minutes.

The total lunar eclipse of 2069 Oct 30 is preceded two weeks earlier by a partial solar eclipse on 2069 Oct 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., TD = UT1 + ΔT). ΔT has a value of 99.3 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 = 4.000

Eclipse Predictions

Predictions for the Total Lunar Eclipse of 2069 Oct 30 were generated using the JPL DE430 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass.

The elliptical shape of Earth's umbral and penumbral shadows were calculated using the Herald/Sinnott method of modeling Earth's shadows to compensate for the opacity of the terrestrial atmosphere (including the oblateness of Earth).

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 99.3 seconds for this eclipse.
