Look out for rare 'super blood blue moon' visible on Jan. 31


A blood moon is a pretty sight to beholdWhat is a super blue blood moon? Making the event even more special is that the moon is at perigee, its closest approach to Earth, creating a "Supermoon" Tuesday night into Wednesday. During this phase the size of the moon appears almost seven per cent larger and its brightness is also higher.

January's full moons are known as a "wolf moon" because historically this month used to be the time when wolves would come out and howl at the sky. Full moons are typically.

To complete the trifecta, this super blue moon will also coincide with a lunar eclipse, or blood moon.

It tweeted yesterday: "What do you get when you have a supermoon, which also happens to be the 2nd full Moon of the month, passing through Earth's shadow during a total lunar eclipse?".

During the eclipse, the moon will glide into Earth's shadow, gradually turning the white disk of light to orange or red.

This is the second supermoon to light up the sky this January.

This is because Native American tribes kept track of the months of the year by the lunar calendar.

Skywatchers and observers all over the world will have the thrill of their lifetime on Wednesday January 31, when the moon while passing through the earth will record the closest distance and appear as 'Blue moon'.

NASA A NASA graphic showcases a timeline for the upcoming eclipse.

In the United States, the best viewing (total lunar eclipse) will be in the Western states.

Johnston advises East Coasters who want to give moon viewing a chance to be outside at about 6:45 a.m. EST.

With the moon setting, make sure you have a non-obstructed view of the western sky.

And several times each year, the sun, Earth and moon line up in a straight line. The eclipse will be visible before sunrise on January 31 for those in North America, Alaska and Hawaii.

The partial eclipse begins at 5:48 a.m. when the moon enters Earth's main shadow, the umbra. According to Gordon Johnston, program executive at NASA, "Weather permitting, the west coast, Alaska and Hawaii will have a spectacular view of totality from start to finish", everyone else's view won't be quite as spectacular. Unlike solar eclipses, a lunar eclipse is not risky to watch and the eclipse may last for hours and be seen in many parts of the world.

Blue moons are not very common because the moon goes through all of its phases once every 28 days. Scientists say the difference between the full moon and the almost full moon is imperceptible to most observers.

Albertans wanting to see one can just look west early Wednesday morning without any kind of help or protection.
