Partial Phases of a Total Solar Eclipse Every total eclipse begins with a series of partial phases which may last an hour or more. However, the total phase or “totality” never lasts more than 7. 5 minutes. This time series photo shows an entire total solar eclipse, from start to finish over a period of over two hours.

Astronomy Picture of the Day - August 13, 1999 Credit: E. Israel Eclipse Shadows When sunlight passes through gaps between leaves of a tree, the shadows on the ground show little images of the eclipse happening in the sky above. This is the same principle as the pinhole camera.

Astronomy Picture of the Day - June 21, 2001 Credit: Fred Espenak “Diamond Ring” Effect Before Totality Begins In the last seconds before totality begins, the remaining bit of Sun resembles a dazzling jewel as the ring-like corona appears.

Total Solar Eclipse Video of the June 21, 2001 eclipse in Africa shows the Diamond Ring Effect as the Sun vanishes behind the Moon and Totality begins. Click on image to play video

The sun’s glorious corona is composed of hot, rarified plasma with a temperature of 1 to 2 million degrees Centigrade. It is only visible during a total eclipse when the Moon hides the Sun’s brilliant disk. Astronomy Picture of the Day - Sept. 15, 1999 Credit: Fred Espenak Glorious Solar Corona

During “totality” the landscape is bathed in an eerie twilight. Bright stars and planets are visible. Astronomy Picture of the Day - 2003 January 08 Credit: Olivier Staiger Eerie Twilight During a Total Solar Eclipse

Only observers within the shadow’s path will see “totality” - outside the path a partial eclipse will be seen.

It’s possible to see a total eclipse from anywhere on Earth. This image was shot in Antarctica in 2003. Astronomy Picture of the Day - 2003 December 08 Credit: Fred Bruenjes Total Solar Eclipse from Antarctica

Partial Solar Eclipse Partial Eclipse of Oct. 14, 2004 (Hawaii) Credit: Fred Espenak Partial eclipses are visible over a much larger part of Earth than total eclipses. So they are seen by many more people.

Annular Solar Eclipse The solar corona is NOT visible during an annular eclipse. The remaining ring of sunlight hides the corona in its glare. Annular Solar Eclipse of May 10, 1994 (Toledo, Ohio)

Frequency of Solar Eclipse Types Eclipses per Year: 2 to 7 Totals per Year: 0, 1 or 2 Partial Annular Total Hybrid Fred Espenak, NASA’s GSFC 35% 33% 27% 5%
