Solar Eclipses in 2009:

 

There are two eclipses of the Sun (an annular eclipse on January 26 and a total eclipse on July 21-22) in 2009. There are no transits of the Sun in 2009.

 

Note: Be careful looking at the Sun. Even when sunlight is dimmed by fog or clouds, it can still damage your eyes. Never view the Sun directly with the naked eye or with any unfiltered optical device, such as binoculars or a telescope! Use safe solar observing techniques to avoid eye damage.

Glossary

Eclipse, solar:

an eclipse in which the Earth passes through the shadow cast by the Moon. It may be total (observer in the Moon's umbra), partial (observer in the Moon's penumbra), or annular.

Eclipse, annular:

a solar eclipse in which the solar disk is never completely covered but is seen as an annulus or ring at maximum eclipse. An annular eclipse occurs when the apparent disk of the Moon is smaller than that of the Sun.

Magnitude of a solar eclipse:

the fraction of the solar diameter obscured by the Moon at the greatest phase of a solar eclipse, measured along the common diameter.

Penumbra:

the portion of a shadow in which light from an extended source is partially but not completely cut off by an intervening body; the area of partial shadow surrounding the umbra.

Umbra:

the portion of a shadow cone in which none of the light from an extended light source can be observed.
