Tonight’s full moon, known as the Wolf Moon in January was also a Penumbral Eclipse. A Penumbral Eclipse is when the Earth blocks the sunlight reaching the moon’s surface, but in this instance, only a small section of the Earth’s outer shadow (known as the Penumbra) covers the moon.
If you look closely, using the moon as a clock face you will notice a darker shadow at between 4 and 5 o’clock.
