Early in the morning on Jan 31, the Earth will be given a rare treat: a supermoon, a blue moon and a full moon, all on the same night of a total lunar eclipse. It will appear 14 per cent larger and about 30 per cent brighter than usual, says Space.com. However, because it is the second full moon in the same month, the phenomenon is also a "blue moon".
And this super blood moon is an extra special occasion because it's blue too. The skies of Nainital will have the most clear and brilliant view of the eclipse. The moon will be just above the horizon by less than a degree, perhaps already set for many area viewers. The last time the three elements combined at the same time was in 1866. The origin of the phrase "blue moon" is unknown and has nothing to do with the actual color of the moon.
Right after midnight, on January 31st, a sequence of lunar events can be observed.
The relative "superness" of a full moon depends on how close it occurs to the perigree - the specific instant in time that the moon and Earth are closest to each other.
Once in a blue moon there's a reason to get up in the middle of the night.
Thus after a gap of 150 years, blue moon, blood moon and super moon are set to occur on the same time.
The eclipse can be observed starting 6:49 p.m. Wednesday, when the moon starts its passage into the earth's shadow called the penumbral eclipse phase.
India will be able to see the lunar eclipse 2018. This usually happens every two to three years, but it happens twice in 2018 - on January 31 and March 31.
But if you are not somewhere you can simply go outside and see it, here is a list of online locations hosting a live webcast of the rare event.
Residents of the western United States, Alaska and Hawaii will have the best chance to see the full lunar eclipse.
"I'm calling it the purple eclipse because it combines the blue moon and a red eclipse", Rich Talcott, a senior editor at Astronomy magazine, said.
The lunar eclipse will be visible before sunrise on Wednesday, Jan. 31. The earth will be directly between the sun and the moon early Wednesday morning.
