Eclipses

There are two sorts of eclipses, solar eclipses and lunar eclipses.
Solar eclipse takes place during New Moon, when Moon hides Sun.
Lunar eclipse takes place during Full Moon, when the Earth shadow meets the Moon.
Eclipses are possible only when conjunction or opposition Moon-Sun is near Moon nodes (Rahu and Ketu).

Eclipse is central (c) when the line that joint center of Moon and center of Sun cross the Earth. Otherwise, it is a non-central (n.c.) eclipse.
It is a total eclipse if there is a band of Earth surface where the Sun is completely hidden.
If the shadow cone is not long enough to reach Earth, an observer set in its alignment will see an annular eclipse.
Intermediate case is possible if during eclipse, the end of the shadow cone reach then leave Earth surface.
Eclipse is then mixed (total/annular).
Eclipse is partial when there is no point in Earth globe where the Sun is completely hidden.
The eclipse can take place in South or North hemisphere.

With Moon, eclipse is partial or total.
Partial if only a part of the Moon cross the Earth shadow.
Total if the entire Moon is in the Earth shadow. As Moon is near us, phenomenon can be seen everywhere the Moon is risen.
