Sunday's nearly full moon drew many eyes to the sky.

That's because right now the moon is appearing as large and bright as it has in nearly 70 years, creating a "supermoon."The last three full moons of 2016 - October, November and December - are supermoons this year. But this month's is unique.November's full moon is the brightest since 1948, according to NASA. The next time the moon will appear this bright will be in 2034.Despite its name, the supermoon is a relatively simple idea. It takes place when the moon is orbiting particularly close to the earth during a full moon.This time around though, the moon's orbit brought it just 221,524 miles away from Earth.The full moon technically took place at 8:52 a.m., according to NASA, but that was after the sunrise. The moon reached its "perigee" - or closest point to the earth, around 6:22 a.m.While that's when the moon appears its brightest, skygazers should still see an impressive moon this evening, weather permitting, NASA official Noah Petro said in a press release.The moon is set to rise right around dusk. That's also the best time to take a picture of the spectacle.NASA suggests that people trying to photograph the supermoon use some kind of reference point in their photos. That way it gives viewers some context of the size of the moon.And if the weather is uncooperative, there will be another chance to view a supermoon, albeit slightly smaller, on Dec. 14.
