It will be visually imperceptible due to the small entry into the penumbral shadow.
During this penumbral lunar eclipse, the moon will only pass into
the Earth’s outer shadow — the penumbra — which is much fainter and more diffuse compared with the much sharper and darker shadow known as the umbra.

Full Corn Planting Moon, or the Milk Moon.
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur
only when the Sun, Earth, and Moon are aligned (in “syzygy”) exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur
the night of a full moon. The type and length of an eclipse depend upon the Moon’s location relative to its orbital nodes. Unlike a solar eclipse, which can
only be viewed from a certain relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of the Earth. A lunar eclipse
lasts for a few hours, whereas a total solar eclipse lasts for only a few minutes at any given place, due to the smaller size of the moon’s shadow. Also
unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions, as they are no brighter (indeed dimmer) than the full
This occurs in a relatively small fraction of lunar eclipses, and the distribution of these
events is uneven, occurring between 0 and 9 times per century. The period of this variation is about 600 years and also correlates with the frequency of total
umbral eclipses and tetrads.
