Glossary

Eclipse, lunar:

an eclipse in which the Moon passes through the shadow cast by the Earth. It may be total (the Moon passing completely through the Earth's umbra), partial (the Moon passing partially through the Earth's umbra at maximum eclipse), or penumbral (the Moon passing only through the Earth's penumbra).

Magnitude of a lunar eclipse:

the fraction of the lunar diameter obscured by the shadow of the Earth at the greatest phase of a lunar 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.

Note: All time moments are given in Universal Time (UT) units.
For Kyiv Local_Time=UT+2^h (and Local_Time=UT+3^h for summer time).
