January 31, becoming a rare momentum for three Superb events that occur simultaneously. NASA identified the three phenomena that form of supermoon, blue moon, and a total lunar eclipse. This highly anticipated event of all people around the world for promising sightings of the moon
The moon on January 31, it will be a supermoon. This event to call the middle months be in perigee, the point closest to the Earth. That is, the moon will be about 14 percent larger and brighter than usual, according to NASA
Supermoon is thus also called blue moon. Why? Because, this is the day of supermoon full moon a second time in January. The full moon is normally 29 days
Each calendar month has only one full moon. Then, when it happens twice like that on 31 January, this event is commonly referred to as blue moon. Blue moon phenomenon is rare because it is an average of two and a half years
"The term blue moon means there are two full moon in a month, but it really depends on where you are," says Fred Espenak, scientist emeritus at the Space Flight Center NASA's Goddard to
But that really makes this blue moon at once supermoon spectacular is the fact that this phenomenon is in unison with the other lunar event today: total lunar eclipse
That means supermoon while blue moon this will pass through the Earth's shadow (umbra). Then, in the event of a total lunar eclipse, the moon will be colored reddish or orange like copper so it was given the nickname blood moon.
With three lunar event encapsulates the conflict trifecta on January 31, 2018 this came the term super blue blood moon. That is, a total lunar eclipse will change second supermoon in January or this blue moon into blood moon orange or red.
