A central lunar eclipse is a lunar eclipse in which part of the Moon passes through the center of Earth's shadow. This type of lunar eclipse typically appears darker than other lunar eclipses. They are relatively rare in the 21st century as there only 24 of them, however they are statistically more common than non central lunar eclipses. In order for a lunar eclipse to classified as a central lunar eclipse, its gamma must be between -0.2725 and 0.2725.
Central lunar eclipses are always total lunar eclipses and have large umbral eclipse magnitude, long duration and small value of gamma.
