Introduction


The Total Lunar Eclipse of 2051 Apr 26 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 2051 Apr 26 at 02:16:28 TD (02:15:02 UT1). This is 2.4 days after the Moon reaches apogee. During the eclipse, the Moon is in the constellation Virgo. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1587.

The eclipse belongs to Saros 132 and is number 32 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.

The total lunar eclipse of 2051 Apr 26 is preceded two weeks earlier by a partial solar eclipse on 2051 Apr 11.

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 86.0 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 = 2.000

Eclipse Predictions

Predictions for the Total Lunar Eclipse of 2051 Apr 26 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 86.0 seconds for this eclipse.
