Supermoon 2017 Tonight: Watch Live Stream Online Here

The Supermoon Challenge“One night I sat up in bed harshly and threw the covers off. My eyes burned from sleeplessness….I dressed quietly….At the front door I hesitated a moment, then stepped out into the warm summer night. The sky surprised me. It was deep blue, the blue of a sorcerer's hat, of night skies in old Technicolor movies, of deep mountain lakes in Swiss countrysides pictured on old puzzle boxes. I remembered my father removing from a leather pouch in his camera bag a circle of silver and handing it to me, and when I held it up I saw through the dark blue glass a dark blue world the color of this night. Suddenly I stepped out of the shadow of the house into the whiteness of the moon. The moon was so bright I could not look at it, as if it were a night sun….already I knew where I was going knew and did not know where I was going, in the sorcerer-blue night where all things were changed….” – Excerpt from “Clair de Lune” by Steven Millhauser from The Knife Throwers (New York Crown Publishers, 1998) Supermoon. When a full Moon's orbit brings it closest to Earth, we have a Supermoon. There is an astronomical term for this: a perigean or perigee syzygy Full Moon (answering the question of why the term Supermoon was coined). And while some cranky astronomers might gripe that Supermoons are a media creation even they admit that Supermoons do appear 14 percent larger and 30 percent brighter than a full Moon at its farthest point from Earth. While not rare, December’s Supermoon will be the largest one in 2017 – so let’s celebrate it! For much of our history, Full Moons have taken the blame for a whole host of occurrences – insomnia, sleepwalking, pregnancy, menstrual cycles, childbirth, seizures, suicide, accidents, criminal mischief and even transformation into werewolves and selkies! It was also credited with miraculous powers: in Northern Ireland people would bring their sick to the lake on a full moon for healing and in Brittany people "drank the moon" to help them conceive. Although modern research hasn't supported these claims, it is undeniable that a glorious and glowing orb in the sky brings magic, leaving one moonstruck: restless, bold, willing to transcend boundaries. The intense luminosity of a Full Moon illuminates an inky night sky just enough to let a little healthy mischief creep in. Think of the Supermoon as a full moon's full moon, so…. let's treat it as a brave lunar gesture before Winter – the last chance of the season to get out and howl. …which leads us to The Supermoon Challenge. Ah, to be moonstruck, drunk on moonshine, full of restless energy, emboldened by a Full Moon. That is what we want to capture with the Challenge. There’s a reason the full Moon is linked to quirky and peculiar behavior – its intense luminosity draws you outside to wander, question, dare. We challenge you to use this powerful moon magic to connect to your people and the universe. So, what are you doing this Supermoon? Send your video, written thoughts, audio recordings. We will kick off the challenge on the evening of November 21st, when the New Moon begins to grow in apparent size, becoming a fully-fledged Supermoon on December 3rd. During the two weeks the Moon appears to grow in size, show or tell us how you are capturing the Moon magic with #supermoonchallenge on Twitter and Facebook, and/or email us at

Tonight is the beautiful 2017 supermoon. But if you can’t get outside and see a clear view of it, or if it’s too cloudy where you are to see this beautiful sight, then you can watch it on the live stream above. A video to watch the beautiful supermoon is above. It starts tonight, December 3, at around 9 p.m. Eastern, provided by This super moon is also called the “Cold Moon” and it is the largest moon of 2017.

The best time to see the supermoon is just after the moon rises (5:15 p.m. Eastern) and right before the sun rises in your area. If you want to know when your local “moonrise” time is, check here. Peak viewing times as the moon is rising are 4:29 p.m. in San Francisco, 5:26 p.m. in New York City, 6:25 p.m. in Honolulu, and 4:28 p.m. in Alaska. Another peak viewing time will be around 3:45 a.m. Eastern on Monday, December 4 (or 8:45 p.m. GMT), when the moon is at its closest to the Earth. Here’s another supermoon live stream you can view below, provided by Virtual Telescope. This one showed the supermoon rising over Rome. It’s already aired:

The largest recent supermoon occurred in last year. It was the closest approach to Earth since 1948. The moon won’t come that close to Earth again until November 24, 2034. This next stream, below, shows the moon rising over Barcelona. This one has also just ended, but it will give you an idea of what to expect later tonight:

LIVE: Watch the supermoon rising over BarcelonaRuptly is live from Barcelona on Sunday, December 3, where a rare ‘supermoon’ can be seen in the sky. A 'supermoon' occurs when the moon becomes full on the same day as its perigee, the point in the moon's orbit when it is closest to the Earth. Supermoons generally appear to be 14 percent larger and 30 percent brighter than the average full moon. Video on Demand: Contact: Twitter: Facebook:

Tonight’s supermoon is the first of a supermoon trilogy. The next two supermoons will be on January 1 and January 31. The supermoon on January 31 is also known as the Blue Moon since it’s the second full moon of January. This will also occur during a total lunar eclipse which also takes place on January 31, 2018.

The supermoon occurs in about one in ever 14 moons. It looks slightly larger and slightly brighter, and definitely catches the eye. In fact, sometimes the difference between a normal full moon and a supermoon are nearly indistinguishable. But experts agree that the best time to view the moon is right as it is over the horizon, because that’s when it appears the largest. In some situations, the supermoon can appear up to 14 percent bigger and 30 percent brighter than a normal full moon. Today’s moon is expected to be 16 percent brighter and 7 percent larger than normal.

The supermoon occurs when a full moon happens at the same time as the perigee of the moon (the point when the moon is closest to the Earth in its orbit.) This shorter distance makes the moon appear larger in the sky. But this moon won’t appear as bright as last November’s supermoon, which was the closest the moon had been to the Earth in 68 years. If you want the best view of the moon, get as far away from ambient light as possible. To take a photo, fit your camera with a telephoto lens and lengthen the shutter time and increase the sensitivity (ISO) to compensate for the lower nighttime light.
