A blue moon is the second full moon of a month - in January, there will be a full moon on New Year's Day and on January 31 - while a supermoon is when the full moon appears larger and brighter to the naked eye.
In spite of the fact that a supermoon appears somewhat bigger in the sky than a full moon, the distinction is nearly incomprehensible for most people to see. According to NASA, "A supermoon is a Moon that is full when it is also at or near its closest point in its orbit around Earth". This isn't as unusual as the saying "once in a blue moon" might imply: Two full moons typically occur in the same month every two and a half years.
In general, the supermoon will appear 14 percent larger and 30 percent brighter than the average moon.
The second full moon, or blue moon, which also comes with a lunar eclipse, will occur on the night of January 31 for most.
From supermoon to blood moon
In this case, the whole event is made even a bit more special by the fact that this supermoon is one of three occurring right in a row. Full moons are usually separated by 29 days, but the extra "blue moon" was able to squeeze in this January, which has 31 days. The ideal time to encounter the Full Moon Supermoon is after moonrise when it is just above the skyline.
A Blue Moon is when two full moons occur in the same month. The eclipse will be visible starting at 5:51am and last about 1 hour and 50 minutes.
It is safe to look at a lunar eclipse, according to NASA. The Earth, Sun, and Moon don't always lie in the same line. The celestial event will be viewable in totality from western North America to Eastern Asia. The moon is pretty cool and worth looking at, no matter what: "The supermoons are a great opportunity for people to start looking at the Moon, not just that once but every chance they have!" "Often cast in a reddish hue because of the way the atmosphere bends the light, totally eclipsed Moons are sometimes called 'blood Moons'".
