Introduction


The Total Lunar Eclipse of 1974 Nov 29 is visible from the following geographic regions:

  • Europe, Africa, Asia, Australia, Pacific, western North America

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 1974 Nov 29 at 15:14:07 TD (15:13:22 UT1). This is 3.6 days before the Moon reaches perigee. During the eclipse, the Moon is in the constellation Taurus. The synodic month in which the eclipse takes place has a Brown Lunation Number of 642.

The eclipse belongs to Saros 125 and is number 46 of 72 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.

The total lunar eclipse of 1974 Nov 29 is followed two weeks later by a partial solar eclipse on 1974 Dec 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 45.3 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 = 15.000

Eclipse Predictions

Predictions for the Total Lunar Eclipse of 1974 Nov 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 45.3 seconds for this eclipse.
