Introduction


The Annular Solar Eclipse of 2081 Mar 10 is visible from the following geographic regions:

  • Partial Eclipse: South America, Africa, Antarctica
  • Annular Eclipse: Chile, Argentina, Ivory Coast, Ghana, Togo, Benin, Nigeria, Cameroon

The instant of greatest eclipse takes place on 2081 Mar 10 at 15:23:31 TD (15:21:44 UT1). This is 2.4 days after the Moon reaches apogee. During the eclipse, the Sun is in the constellation Aquarius. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1957.

The eclipse belongs to Saros 131 and is number 54 of 70 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 solar eclipse of 2081 Mar 10 is a relatively long annular eclipse with a duration at greatest eclipse of 07m36s. It has an eclipse magnitude of 0.9304.

The annular solar eclipse of 2081 Mar 10 is followed two weeks later by a partial lunar eclipse on 2081 Mar 25.

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 106.4 seconds for this eclipse.

Global Map Animation of Solar Eclipse

Michael Zeiler GreatAmericanEclipse.com and
Fred Espenak EclipseWise.com have created a series of eclipse animations - one for every solar eclipse during the 21st Century.

The animation of the Annular Solar Eclipse of 2081 Mar 10 shows the path of the Moon's shadows as they sweep across a global map of Earth (an orthographic projection). The vantage point of the animation is as seen from the Moon. The daylight hemisphere of Earth then faces the Moon and the lunar shadows appear perfectly circular with no distorted projection effects as they race across Earth.

The Moon's antumbral shadow appears as a small black disk and tracks along the path of annularity (yellow strip). The much larger penumbral shadow is lightly shaded and is outlined with a solid black edge. A partial eclipse is visible from within the penumbra, while an annular eclipse is visible inside the antumbra. Another consequence of this viewing geometry is that the Moon's shadows move across the disk of Earth in a straight line.

The map to the right shows a single frame from the medium size animation for the Annular Solar Eclipse of 2081 Mar 10 . In the upper left corner is the type of eclipse and the eclipse date. To the upper right is the Universal Time. The lower left corner displays the instantaneous duration of annularity. To the lower right is the credit for the animation.

Animations for the Annular Solar Eclipse of 2081 Mar 10 are available in three sizes/resolutions: small, medium, and large. They can be viewed through the following links:

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 2081 Mar 10 were generated using the JPL DE405 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 106.4 seconds for this eclipse.
