Penumbral eclipses are slight, verging on imperceptible in some instances, says Jackie Faherty, an astrophysicist on the American Museum of Pure Historical past in New York. “It’s not one thing that’s going to slap you within the face.”

So Sunday night time’s eclipse won’t be as dramatic as a complete lunar eclipse, during which the moon plunges into Earth’s darkish internal shadow, referred to as the umbra, turning its floor blood pink. Neither is it as putting as a partial lunar eclipse, during which the moon slides behind a part of the umbral shadow and appears as if some area monster took a huge cookie chunk out of it.

And it’s not as awe-inspiring as a complete photo voltaic eclipse, during which the brand new moon glides in entrance of the solar, leaving a wispy, white halo shining within the daytime sky.

However the penumbral eclipse might nonetheless be value your time as an opportunity to check how attuned you might be with the night time sky, Dr. Faherty stated. For our ancestors who lived with out metropolis lights or streetlamps, the moon offered nearly all of helpful mild at night time. If it dimmed ever so barely, folks observed.

However that perceptiveness has been misplaced partially as our dependence on the moon’s glow has waned. Dr. Faherty suggests utilizing the penumbral eclipse to check your senses.

However in the event you’re nonetheless not bought on watching the penumbral eclipse, then maybe you may take away this nifty truth from its look: It’s the harbinger of the following whole photo voltaic eclipse. Lunar eclipses and photo voltaic eclipses are celestial peas in a pod. As soon as one seems, the opposite will observe two weeks later. And on Dec. 14, there can be a complete photo voltaic eclipse whisking over components of Chile and Argentina.
