Introduction


The Annular Solar Eclipse of 2014 Apr 29 is visible from the following geographic regions:

  • Partial Eclipse: south Indian, Australia, Antarctica
  • Annular Eclipse: Antarctica

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 2014 Apr 29 at 06:04:33 TD (06:03:26 UT1). This is 6.2 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Aries. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1130.

The eclipse belongs to Saros 148 and is number 21 of 75 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 annular eclipse is very unusual in that it is NON-CENTRAL and does NOT have a central line nor a southern path limit. Instead , over half of the antumbral shadow falls off into space throughout the eclipse. Gamma has a value of -1.0000.

The annular solar eclipse of 2014 Apr 29 is preceded two weeks earlier by a total lunar eclipse on 2014 Apr 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., UT1 = TD - ΔT). ΔT has a value of 67.3 seconds for this eclipse.

The following links provide maps and data for the 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 2014 Apr 29 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 2014 Apr 29 . 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 2014 Apr 29 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 2014 Apr 29 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 67.3 seconds for this eclipse.
