If you can see the Moon tonight, over the next few hours it’s going to start looking pretty awesome. This #LunarEclipse starts really getting going a few minutes from now and gets to maximum in a little over an hour. Timing info & visibility maps: timeanddate.com/eclipse/lunar/… A map of eclipse visibility. Basically the entire half of the globe centered around Cuba.
A total #LunarEclipse is when the Moon, Earth, and Sun line up perfectly enough that the Moon is entirely in the Earth’s shadow. Here’s a handy graphic:
When the Moon starts to enter the Earth’s shadow, it’ll look like part of the Moon is going dark, in contrast to the section just outside the shadow, still brightly lit. But when it’s ENTIRELY in the shadow, you’ll see something else, much cooler. #LunarEclipse
During totality, when the whole Moon is in shadow, instead of it disappearing completely, it turns a deep red. This light is the red glow of all the world’s sunsets and sunrises — the only light reaching the Moon when it’s in shadow. From the Moon, the Earth looks ringed in fire.
The red glowing Moon seen during a total #LunarEclipse is the reason for the (fairly recent) monicker “blood moon.” I guess it sounds catchy, and to be fair, it can look a bit gruesome. earthsky.org/human-world/wh… (Image: MrEclipse.com) A deep red Moon, darker on the lower left
Lately, it’s been fashionable to add extra names to each #LunarEclipse. This one gets “wolf” from “Wolf Moon,” an old-fashioned name for a January full moon, & “super” from the being Moon at its closest point in its orbit, so it looks (slightly) bigger. #SuperBloodWolfMoon
Q: Is it OK to look at a #LunarEclipse with the naked eye?
A: Yes! Best way to see it. Look up & enjoy!

Q: How often do lunar eclipses happen?
A: Few times a year

Q: Will the #SuperBloodWolfMoon awaken warewolves/bring about the apocalypse?
A: The Moon claims no responsibility
