A total lunar eclipse will be visible in Alberta Wednesday

The challenge for central OH viewers will be two-fold: increasing high clouds during the pre-dawn hours on Wednesday, and the narrow window to view the partial lunar eclipse, locally. The best time to view it will be from 5 a.m.to 6 a.m.

Based on Nolle's theory, the moon would have to be 226,000 miles away from the Earth to be considered "super".

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.

This spectacle occurs when the earth comes directly between the sun and the moon.

Nasa said the eclipse will offer scientists a chance to see what happens when the surface of the moon cools quickly.

The "super blue blood moon" will be most visible to people on western part of North America, Alaska, and the Hawaiian islands, according to Gordon Johnston, program executive and lunar blogger at NASA.

"The eclipse will start at 6.51pm on Jan 31 when the Earth's penumbra start touching the moon's face, while at 7.48pm partial moon eclipse begins where the moon is getting red".

The Supermoon phenomenon occurs when a full moon is at the nearest position to earth in its orbit, making it appear larger than normal.

What is a full moon?

Before people knew the reason for this, people feared a blood moon, seeing it as an act of God.

A blue moon - is the song in your head yet? - is simply the second full moon in the same month. "The overall eclipse ends at 12.08 midnight on Feb 1", he explained.

In the Rocky Mountain region, the show begins as the umbra touches the edge of the Moon at 4:48 a.m. MST.

If you miss the January 31 lunar eclipse, you'll have to wait nearly another year for the next opportunity in North America. Long after the socializing fell by the wayside, Johnston's monthly blog lives on, with a dedicated following on NASA's lunar website, moon.nasa.gov.

"There will be about six members with telescopes on different objects for when it gets darker, so we encourage everyone to get out here, bring their own chairs and picnic stuff if they wish and make a night out of it".

Love to observe the Moon?

A lunar eclipse happens several times of year, so it's not that uncommon.

"Sometimes the celestial rhythms sync up just right to wow us", NASA says. It will be visible before sunrise on 31 January from western North America, and because of the worldwide date line, after sunset on 31 January from central and eastern Asia, Indonesia, New Zealand and most of Australia.
