An eclipse is an astronomical event that occurs when one object in the sky moves into the shadow of another. The term is most often used to describe either a solar eclipse, i.e. when the Moon’s shadow crosses Earth’s surface, or a lunar eclipse, i.e. when the Moon moves into the shadow of Earth.
A recent excellent article describes eclipses and how to view them. Another website gives more detailed info about future lunar and solar eclipses to occur up to 2020 and the geographic region of visibility.
This sky event is known to play a significant role in lives of individuals, corporations and nations. According to Vedic astrology the impact of eclipse is focused on the region of its visibility. The influence of eclipse in individual life depends completely upon the house and sign in which the eclipse occurs, and upon any close planetary aspects that may also occur.
On Friday, 2008 August 01, a total eclipse of the Sun is visible from within a narrow corridor that traverses half the Earth. The path of the Moon’s umbral shadow begins in Canada and extends across northern Greenland, the Arctic, central Russia, Mongolia, and China.
A partial eclipse is seen within the much broader path of the Moon’s penumbral shadow, which includes northeastern North America, most of Europe and Asia. The Aug. 1 eclipse may presage major events in China (We know the Summer Olympics begin Aug. 8 ) and other regions over which the eclipse is visible. Those who live in these areas with sidereal lagna (ascendant), moon or sun in cancer between 14 to 16 degrees may be adversely affected. Implications for individuals can be detailed only after analysis.
