Watch for 'Super' Full Moon Tonight

It might be worth taking a peek out the window tonight at what many are calling a 'supermoon.'

A super "perigee moon" will rise in the east at sunset and be about 15 percent larger than usual, according to a NASA Science News article. It will be closer to the Earth than it's been in 18 years.

From the article:

Full Moons vary in size because of the oval shape of the Moon's orbit. It is an ellipse with one side (perigee) about 50,000 km closer to Earth than the other (apogee). Nearby perigee moons are about 14 percent bigger and 30 percent brighter than lesser moons that occur on the apogee side of the Moon's orbit.

"The full Moon of March 19 occurs less than one hour away from perigee—a near-perfect coincidence that happens only 18 years or so," Geoff Chester of the US Naval Observatory in Washington, D.C. said in the article.

Higher tides, "perigean tides," could come with the perigee full moon, but only up to about six inches at most.

The best time to look, according to NASA Science, is when the moon is near the horizon.

And although it might seem close enough to touch, the NASA report explained, even a super perigee moon is still 356,577 km away.
