PI, the ratio of a circle to its diameter is about 3.14 and for some neo-cultural reason we now celebrate “PI Day” on March 14th of each year. Those of us who score very well on the Nerd Test, can appreciate this nerdy quasi-holiday.
As it turns out, we had sort of a coincidence overnight when the Moon became obscured by the Earth’s shadow (umbra). Damsel and I observed the phenomenon after midnight just before hitting the hay.
SpaceWeather.com posted the image below on their website of the Moon, as seen from Earth and the Earth as seen from the Moon during the eclipse. The Blue Ghost lunar lander took the earthward image seen on the right side of the composite image.
Astronomy Picture of the Day posted the explanation that when an eclipse of the Moon occurs the angle between the Sun and the Moon from Earth’s perspective is approximately 3.14 Radians (180°).
Happy Moon PI Day!
