Penumbral Lunar Eclipse
This first lunar eclipse of the year shot at 8-18PM today at ISO 50. The shadow of the Earth can be divided into two distinctive parts: the umbra and penumbra. Within the umbra, there is no direct solar radiation. However, as a result of the Sun’s large angular size, solar illumination is only partially blocked in the outer portion of the Earth’s shadow, which is given the name penumbra.
A penumbral eclipse occurs when the Moon passes through the Earth’s penumbra. The penumbra does not cause any noticeable darkening of the Moon’s surface, though some may argue it turns a little yellow. A special type of penumbral eclipse is a total penumbral eclipse, during which the Moon lies exclusively within the Earth’s penumbra. Total penumbral eclipses are rare, and when these occur, that portion of the Moon which is closest to the umbra can appear somewhat darker than the rest of the Moon.
