A supermoon will be visible in the skies over OR on New Year's Night, providing the illusion of being a larger moon. The second full moon in a month is called a "blue moon".
January 31's supermoon, according to the space agency, will also feature a total lunar eclipse - when the Earth, sun and moon, line up in such a way that the Earth blocks the sunlight that would otherwise reflect off the moon.
From two supermoons, a meteor shower to a lunar eclipse, here's a list of astronomical events for the first month of 2018.
Tonight's full moon is the closest and brightest of the year.
Meanwhile, a lunar eclipse, a point at which the moon passes behind the Earth into its umbra (shadow), will begin at 6:51 p.m. on January 31 and will be best observed in Taiwan between 8:51 p.m.to 10:08 p.m., said the observatory.
With the total eclipse, it will be a royal spectacle indeed, a "super blue blood" moon, NASA said. Peak viewing times for the rising of the moon are 5:04 p.m.in San Francisco, 4:34 p.m.in New York City, 6:06 p.m.in Honolulu, and 4:15 p.m.in Anchorage, Alaska.
The moon will lose its brightness and take on an eerie, fainter-than-normal glow from the scant sunlight, giving it a reddish hue. But it will occur very late, when the moon is close to the earth's horizon.
The full moon on January 2 was also a super moon because it was within 361,000 kms.
You can watch webcasts of January's New Year's Day supermoon live today and tonight. It was the closest approach to Earth since 1948.
The moon just like the Earth does not have a completely round orbit. If you want the best view of the moon, get as far away from ambient light as possible.
A typical Supermoon is about 16% brighter and 7% larger than an average full moon.
