Here's how to watch Sunday's Supermoon Eclipse

Some celestial phenomena happen regularly, but infrequently, and you may only get a few chances to see them during your lifetime. A supermoon lunar eclipse is one such event, a time when the moon is both at its closest to the Earth and when it passes into our planet's shadow, causing a lunar eclipse. The last time this event happened was back in 1982, and if you happened to have missed it (or weren't born yet), September 27 will be your next shot at witnessing the supermoon event.

As always, NASA will be watching the event and will do everything it can to make sure you can see it, too, if doing so in person isn't possible. The space agency will be live streaming the supermoon lunar eclipse starting at 8PM EDT and running up through at least 11:30 EDT. Hit up this link to watch the supermoon at that time.

NASA will be broadcasting from the Marshall Space Flight Center in Alabama; the live feed will be coming from the Griffith Observatory in LA, however. During that time, one of NASA's physicists will be taking questions and talking about the eclipse on Twitter under the #askNASA hashtag.

If you'd rather see the supermoon lunar eclipse with your own eyes, you'll need to be located in North/South America, Europe, Africa, or select parts of West Asia and the eastern Pacific, says NASA. Assuming clouds don't get in the way, you'll be able to see the moon once it gets dark, and will see the eclipse at approximately 8:11PM EDT. The full eclipse will span from about 10:11PM to 10:47PM EDT.
