During the event , when the Sun will be direct behind us in respect to the Moon , the lunar Earth’s surface will come along a deep ruby-red color . Lunar eclipses are fairly usual , with 16 occurring this century already , but only five supermoon occultation have take position since 1900 .
It will be well visualize at every longitude from the U.S. to Europe , embrace Central and South America , the U.K. and Africa . Observers in western Asia and Alaska will have a lesser panorama . train outthis mapat timeanddate.com to see the best position .
The integral event will last about five hours , but there are only about 70 minute when the Moon will seem red . At 8:11 p.m. EDT on Sunday , the Moon will begin to enter Earth ’s shadower , giving it a tenuous yellowish chromaticity . From 10:11 p.m. to 11:23 p.m. EDT , the eclipse will reach totality , do the Moon appear a cryptic redness , and at 1:23 a.m. EDT on Monday , it will kick the bucket Earth ’s phantasm .

The reason the Moon appears cherry-red , sometimes labeled a “ blood moonlight , ” is due to the refraction , or bend , of sun in Earth ’s atmosphere . cogitate about a sunrise or sunset – the more atmosphere light has to travel by through , the more it refracts towards the red end of the electromagnetic spectrum . During a lunar eclipse , light from the Sun refract through the atmosphere and strike the lunar open , making it seem red .
As refer , this occultation is specially peculiar because it coincides with a “ supermoon . ” The Moon ’s orbit around Earth is not perfectly circular ; it ranges from 363,000 kilometers ( 226,000 miles ) to 406,000 kilometers ( 252,000 naut mi ) . On Sunday night , it will be near its closest point , appearing 14 % orotund than an mean Moon .
To the au naturel eye , this size departure is n’t very noticeable . If you see the Moon near the horizon , though , you may acknowledge that it appear huge . This is n’t due to its aloofness , but rather an effect known as theMoon illusion , where your brain perceive the Moon to be closer at the horizon than up above , thus overcompensating and tricking you into think it is bigger .
This NASA video recording explain how a supermoon lunar eclipse do work .
This result is also the last of a episode of four total lunar eclipses , which is known as a lunar four . The first was on April 14 , 2014 , the second October 7 , 2014 , and the third April 4 , 2015 . These are considerably rarified than eclipses by themselves – only 50 lunar tetrads have happen in the past two millenary .
