The full moon in November of this year will have an advantage: a penumbral lunar eclipse, which will occur on Monday 30. The moon will be at its maximum only for a moment, Monday (at 9:30 UTC), but the it will appear full for three days: from Saturday evening to Tuesday morning.
Penumbral eclipses are different from total or partial eclipses.
During a total lunar eclipse, the Earth passes directly between the Sun and the Moon, preventing sunlight from reaching our natural satellite. Conversely, during a partial eclipse, the Moon passes through part of the Earth’s internal dark shadow, known as the shadow. Finally, in a penumbral eclipse, the Moon passes through some of the faintest outer penumbral shadows on Earth.
Unless one is an experienced observer of the sky, it can be difficult to watch the November penumbral eclipse, because the penumbra shadow will appear as a faint veil. “The darkening of the moon during this eclipse will probably not be evident without instrumentation, but for spacecraft on the moon such as the Lunar Reconnaissance Orbiter (LRO), the reduction in solar energy will be significant,” NASA explained.
The full moon in November is known to many as the beaver moon. Other names for the moon include cold moon, icy moon, winter moon, and oak moon.
And for those who miss the November full moon, they will have one more chance, as the last full moon of 2020 will happen between December 29th and December 30th.
