Jan 26, 2009 Annular Solar Eclipse

The animation shows where this annular solar eclipse is visible (white, gray and red shading) as well as day and night (dark “wave” slowly moving across the Earth's surface).

The colors within the shaded area show how much of the Sun's disk the Moon covers during the eclipse. The dark center of the red area shows the best locations to view this eclipse. Here, the Moon moves centrally in front of the Sun without covering it entirely, leaving a bright “ring of fire” that is characteristic of an annular solar eclipse.

In the red area, the Sun is obscured 90 percent or more, in the dark gray area the Moon covers between 25 and 90 percent of the Sun's disk. The white shaded area symbolizes locations where less than 25 percent are covered.

The dark strip in the center indicates the best locations for viewing the eclipse. Here, the Moon moves centrally in front of the Sun.

The eclipse is also visible in the areas that are shaded red, but less of the Sun's disk is obscured. The fainter the red shading the less of the Sun's disk is covered during the eclipse.
