What makes the super moon also a blue moon is the ideal, dual timing of the second full moon of the month (a blue moon) - a rare occurrence in itself - and the moment when the moon is closest to Earth in its orbit, making it appear bigger and brighter than usual. January 31st will see a total lunar eclipse, which will be best visible on the west coast. The following infographic from Space.com explains the blue moon.The event will be observed well in central and eastern Asia, Indonesia, New Zealand and Australia.
The "blue blood moon" will be visible mostly in Alaska, Hawaii, and select parts of the western U.S. For watchers in order parts of the mainland U.S., only a partial eclipse will be visible. There has already been one full moon this month - the supermoon that was visible in the evening of the 1st and early morning of the 2nd.
But know that these names can make an event like this sound more dramatic than it appears - it won't be anything like the total solar eclipse of 2017.
Besides, the moon on January 31 will appear bigger and brighter as it will be a super moon.
According to NASA, a blue moon happens every two-and-a-half years.
The way the light filters through the atmosphere during an eclipse causes the blue light to bounce away from the moon, reflecting red light. This is a common term for the second full moon in a month. During eclipses, the moon will get a dark reddish color like rust, as our planet's satellite will enter the Earth's shadow, which will interfere between the Sun and the Moon. To answer that question, we consulted the reference book Canon of Lunar Eclipses, 1500 B.C. - A.D. The moon experiences perigree once per orbit, but that doesn't always coincide with a full moon.
Three separate celestial events will occur simultaneously that night, resulting in what some are calling a super blue blood moon eclipse. That stunning event will lead to the moon turning a deep, rich red, a sight that has led to it being christened the "blood moon".
Scientifically, Simpson said, the event is pretty meaningless.
