Introduction


The Total Solar Eclipse of 2084 Dec 27 is visible from the following geographic regions:

  • Partial Eclipse: Africa, Antarctica, Australia
  • Total Eclipse: South Atlantic and Indian Ocean

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 2084 Dec 27 at 09:13:48 TD (09:11:56 UT1). This is 0.9 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Sagittarius. The synodic month in which the eclipse takes place has a Brown Lunation Number of 2004.

The eclipse belongs to Saros 133 and is number 49 of 72 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 solar eclipse of 2084 Dec 27 is followed two weeks later by a penumbral lunar eclipse on 2085 Jan 10.

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 112.3 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 = 9.000

Eclipse Predictions

Predictions for the Total Solar Eclipse of 2084 Dec 27 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 112.3 seconds for this eclipse.
