Rare Supermoon Lunar Eclipse Takes Place this Sunday Evening!



With the huge supermoon lunar eclipse happening this Sunday evening, it's time to dust off your small telescopes and binoculars, track down an observatory event or webcast, 

or draft your invitations for a moon-cake party.  Don't wait too long — if you miss it, the next one isn't until 2033.

The supermoon lunar eclipse of 2015 will occur Sunday, Sept. 27, and is a confluence of three events: a full moon; a lunar eclipse, in which the Earth blocks the sun's light from hitting the moon; and lunar perigee, when the moon is in the closest part of its orbit to Earth. The last time such a confluence happened was in 1982; there were just five instances of it in the 20th century. This time around, viewers looking from the Americas, Europe, Africa, western Asia and the eastern Pacific Ocean will have a chance to see the show.

During lunar perigee, the moon appears larger and brighter in the sky, which is why a full moon coinciding with perigee is known as a "supermoon." (A "minimoon" is when the full moon is at its farthest point from the Earth.) This large moon will present the perfect canvas to watch the Earth's shadow slide over and block the moon's light.


As if that weren't spectacular enough, there's the origin of the eclipse's other name, "blood moon." The moon doesn't simply disappear into Earth's shadow during a lunar eclipse; instead, it's illuminated by an eerie, reddish glow of the light refracting through the edges of Earth's atmosphere.














The moon will be shrouded in shadow Sunday night or early Monday morning (depending on the time zone). It will enter the dark part of the Earth's shadow at 9:07 EDT Sunday (0107 GMT), and it will enter a total eclipse by 10:11 p.m. EDT (0211 GMT Monday) before beginning to emerge from shadow 12 minutes later. Areas that cannot see the full eclipse, because sunset comes too late or sunrise too early, may still be able to see part of the moon obscured.

Watch NASA’s live stream from 8:00 p.m. until at least 11:30 p.m. EDT broadcast from Marshall Space Flight Center in Huntsville, Ala., with a live feed from the Griffith Observatory, Los Angeles, Calif. Mitzi Adams, a NASA solar physicist at Marshall will discuss the eclipse and answer questions from Twitter. To ask a question, use #askNASA.





Throughout human history, lunar eclipses have been viewed with awe and sometimes fear. Today, we know that a total lunar eclipse happens when the full moon passes through the darkest part of Earth's shadow, the umbra.
Sunday’s supermoon eclipse will last 1 hour and 11 minutes, and will be visible to North and South America, Europe, Africa, and parts of West Asia and the eastern Pacific. Weather permitting, you can see the supermoon after nightfall, and the eclipse will cast it into shadow beginning at 8:11 p.m. EDT. The total eclipse starts at 10:11 p.m. EDT, peaking at 10:47 p.m. EDT.


Of course, in addition to the telescope, binoculars and webcast viewing methods, the eclipse can be seen with the old-fashioned naked eye — so be sure to look up!

By the way - There are several Christian groups proclaiming that this is a sign the Jesus is returning this Sunday and the rapture may occur.  If so, I will not be at church next Sunday - but hope to see you in Heaven!
