A total lunar eclipse will be visible in Alberta Wednesday


What is going to make this special is going super blue moon. The first is any time a second full moon occurs in a single month. The full event will take over four hours and the moon will be fully eclipsed by Earth's shadow for around an hour and 16 minutes.

The Moon looks like getting darker during a total eclipse, as our natural satellite is moving into the Earth's shadow.

Let's break down this rare celestial phenomenon.

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.

He further explained that a super moon has an effect on the height of tides but has no correlation or effect on Mayon Volcano's eruption. This blood moon will also be a supermoon because it's closer to earth: it will appear slightly larger and slightly brighter than a typical full moon.

First, this week's full moon is a supermoon.

This definition was actually a mistake made by amateur astronomer James Hugh Pruett, who called it the second in a month in an article written for Sky and Telescope Magazine in 1946.

As if we didn't have enough Moons to think about, here's another one - the "Mini Moon" or "Micro Full Moon" on July 27.

Though not quite astronomical odds, the chances of all three events occurring together are less than, well, once in blue moon - which incidentally occurs about once every 2.7 years, said Jason Aufdenberg, a professor of physics and astronomy at Embry-Riddle Aeronautical University. The changes in temperature will happen more quickly than they do in a regular lunar day, a little less than 30 Earth days.

A super moon, however, usually occurs before or after the occurrence of a blue moon or lunar eclipse. The last time it happened in the Americas was March 1866.

Here are the eclipse details for Minneapolis via timeanddate.com.

The best viewing for the event in Southern Wisconsin will be early Wednesday morning from 4:50 a.m. until 7:13 a.m., with the best viewing before morning twilight around 6 a.m. Clouds may linger over the Twin Cities.

That means that if you live in the Eastern part of the United States, your best bet is to get as high as you can and have a clear line of sight to the horizon in the west-northwest.
