Super Blood Wolf Moon Eclipse Dates: What Time Moon Turns Red

A supermoon and total lunar eclipse will coincide Jan. 20-21 in a rare celestial occurrence that will be visible across North America. Whether you’ll be able to see this event — also known for reasons we’ll get into later as a “blood moon” and a “wolf moon” — is dependent on the weather, of course.

A total lunar eclipse, which only happens during a full moon, occurs when the Earth moves between the sun and the moon, blocking the sunlight normally reflected by the moon, NASA explains.

The Earth’s shadow falls on the entire moon and the orb takes on a dark red or copper color — hence the “blood moon” part of this celestial event — as it is illuminated by sunlight filtered and refracted by the Earth’s atmosphere.

There’s no need to take special precautions to protect your eyes to view the total lunar eclipse, as you would during a solar eclipse. Just look up in the sky and enjoy it.

On Sunday night, start watching the skies about 10:30 p.m. Eastern Standard Time as the Earth’s shadow begins passing in front of the moon from the lower left. Totality begins at about 11:41 p.m. Eastern Standard Time and continues for about an hour until 12:43 a.m. on Monday, when the moon returns to its normal appearance.

Normal, though, is in the eye of the beholder in this case. Because it’s a supermoon — a recently popularized term describing the phenomenon that occurs when a full moon coincides with the moon’s closest approach to Earth, or perigee — it will appear larger than normal.

Lunar eclipses that occur during supermoons are rare, making this one extra special because it comes almost a year after the Jan. 31, 2018, super blood moon — also a blue moon, because it was the second full moon (and supermoon) of the month.

Having two full moon blood moons in back-to-back years is an oddity, NASA planetary scientist Rick Elphic told Time magazine.

“It’s usually years between lunar eclipses that have supermoons in them,” Elphic said. “We just happen to be in a seasonal cycle where last year there was one and then this year, there is one and I don’t think there will be another supermoon eclipse for a while.”

Early Native American tribes called the January full moon the “wolf moon” because it was the time of year when hungry wolves howled near their camps. However, the Farmers’ Almanac notes that the notion of wolves howling at a full moon is “known to be more folklore than fact.”

Some cultures refer to the first moon after Christma as the “moon after yule.”
