This will be the second full moon in a month, also called the Blue Moon.
People will also be able to witness the total lunar eclipse on January 31.
"The supermoons are a great opportunity for people to start looking at the moon, not just that once but every chance they have", said Noah Petro, a research scientist at NASA's Goddard Space Flight Center.
But if you miss tonight's moon - never fear, the January 31 moon will be "extra special" according to Nasa.
If skies are clear, Bonadurer will bring the museum's telescopes to the roof of the Urban Ecology Center at Riverside Park, 1500 E. Park Place, from 5:30 a.m.to 7 a.m. on January 31 for anyone who wants to see the blue moon total eclipse.
A supermoon is a full moon which occurs when the Moon is closest to the Earth, making it appear bigger and brighter.
Perigee is an astronomical term that identifies the nearest distance of the moon to the earth.
This evening, pictures show the blood-red moon rising over Tynemouth, Tyne and Wear. "Like when you go from 100 to 150 watts; I thought the moon was going to appear noticeably brighter last night, but it really wasn't at all!"
In other moon news, there's a supermoon tonight.
The full moon on January 2 was also a super moon because it was within 361,000 kms. It was the closest approach to Earth since 1948. "It didn't look at all brighter than normal".
You can watch webcasts of January's New Year's Day supermoon live today and tonight.
The first and last supermoon of 2017 didn't happen until December, but in 2018 the wait won't last past New Year's Day. And the margin for a supermoon seems to be widening, as full moons that occur within one or two days of perigee are sometimes given the "super" moniker.
