Solar Eclipse 2014

Solar Eclipse Frequency and Future Eclipses

During the five thousand year period 2000 BCE to 3000 CE, planet Earth experiences 11,898 solar eclipses as follows:

All Eclipses-11898100.0%
PartialP420035.3%
AnnularA395633.2%
TotalT317326.7%
HybridH5694.8%
This works out to an average 2.4 eclipses each year. Actually, the number of solar eclipses in a single year can range from 2 to 5. Nearly 3/4 of the time there are 2 eclipses in a year. On the other hand, it is quite rare to have 5 solar eclipses in a single year. The last time it happened was in 1935 and the next time is 2206. Typically there is 1 total eclipse every 1 to 2 years. Although it is possible to have 2 total eclipses in a single year, it is quite rare. Examples of years containing 2 total eclipses are 1712, 1889, 2057 and 2252.
The table below lists every solar eclipse from 2009 through 2015. Click on the eclipse Calendar Date to see a global map showing where the eclipse is visible from. The Eclipse Type link opens a window showing the path of total and annular eclipses plotted on Google Maps. The Eclipse Magnitude is the fraction of the Sun's diameter covered by the Moon at greatest eclipse. For total and annular eclipses, this value is actually the ratio of the apparent diameters of the Moon to the Sun. The Central Duration lists the duration of totality or annularity at greatest eclipse. The link produces a table of geographic coordinates of the eclipse path. The last column is a brief description of the geographic regions of eclipse visibility. The descriptions in bold are for the paths of total or annular eclipses.
