total lunar eclipse

Partial lunar eclipse.

Explanation:

A lunar eclipse is a cosmological event by which, in the presence of the Earth between the Sun and the Moon, the latter does not receive the light of the Sun in the totality of its visible face, with which a part (or the totality ) of her is in the dark.

Thus, if the lunar eclipse implies an absence of sunlight in the entire lunar surface, the eclipse will be total, while if the eclipse implies an absence of light only in part, the eclipse will be partial (which is the most common event).
