Introduction


The Partial Solar Eclipse of 2098 Apr 01 is visible from the following geographic regions:

  • Partial Eclipse: Antarctica, South America

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 2098 Apr 01 at 20:02:31 TD (20:00:29 UT1). This is 6.1 days after the Moon reaches apogee. During the eclipse, the Sun is in the constellation Pisces. The synodic month in which the eclipse takes place has a Brown Lunation Number of 2168.

The eclipse belongs to Saros 121 and is number 65 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.

This is a very deep partial eclipse. It has an eclipse magnitude of 0.7984, while Gamma has a value of -1.1005.

The partial solar eclipse of 2098 Apr 01 is followed two weeks later by a total lunar eclipse on 2098 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 121.9 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 Partial Solar Eclipse of 2098 Apr 01 shows the path of the Moon's penumbral shadow as it sweeps 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 large penumbral shadow is lightly shaded and is outlined with a solid black edge. A partial eclipse is visible from within the penumbra.

The map to the right shows a single frame from the medium size animation for the Partial Solar Eclipse of 2098 Apr 01 . 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 is not used for partial solar eclipses. To the lower right is the credit for the animation.

Animations for the Partial Solar Eclipse of 2098 Apr 01 are available in three sizes/resolutions: small, medium, and large. They can be viewed through the following links:

Eclipse Predictions

Predictions for the Partial Solar Eclipse of 2098 Apr 01 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 121.9 seconds for this eclipse.
