Mark Wednesday, Feb. 20, on your calendar as "Lunar Eclipse Night," for if the weather is fair you should have no difficulty observing a total eclipse of the moon.

The eclipse will be visible wherever the moon is above the horizon during the time frame that the eclipse is taking place. As it turns out, North and South America will be turned toward the moon and will be in excellent position for this sky show.

Europe, Africa and a part of western Asia will also be able to see the eclipse, although for these regions the event will take place in the hours just before sunrise on the morning of Feb. 21.

All told, given clear skies, about three billion potential eclipse viewers will be able to partake in the spectacle of the full moon becoming completely immersed in the Earth's shadow.

This will be the third total lunar eclipse within the past year. The previous two favored different parts of North America, but this one will be readily visible from start-to-finish across much of the continent, weather permitting.

The total phase will last 51 minutes and begins at 10:01 p.m. ET.

Because some of the sunlight striking the Earth is diffused and scattered by our atmosphere, the Earth's shadow is not completely dark. Typically there are coppery red and orange hues cast over the moon at and near totality from sunlight refracted from our atmosphere around the edge of the Earth, giving the moon the appearance of an eerie glowing ball.

As a bonus, during the eclipse the moon will be situated, in our sky, near the planet Saturn and the bright bluish star Regulus in the constellation of Leo. The effect will be to create a uniquely beautiful triangle in the sky consisting of the totally eclipsed moon, a bright naked-eye planet and one of the 21 brightest stars in the sky.

On Wednesday night, Feb. 20, for the third time in the past year, the moon will become completely immersed in the Earth's shadow, resulting in a total lunar eclipse.

As is the case with all lunar eclipses, the region of visibility will encompass more than half of our planet. Nearly a billion people in the Western Hemisphere, more than 1.5 billion in Europe and Africa, and perhaps another half-billion in western Asia will be able to watch — weather permitting — as the brilliant mid-winter full moon becomes a shadow of its former self and morphs into a glowing coppery ball.

Almost everyone in the Americas and Western Europe will have a beautiful view of this eclipse if bad weather doesn't spoil the show. The moon will be high in a dark evening sky as viewed from most of the United States and Canada while most people are still awake and about.

Local conditions

The only problematic area will be along the Oregon and northern California coast, where the first partial stage of the eclipse will already be under way when the moon rises and the sun sets on Wednesday evening. But if you have an open view low to the east, even this situation will only add to the drama, for as twilight fades, these far-Westerners will see the shadow-bitten moon coming into stark view low above the landscape. And by late twilight observers will have a fine view of the totally eclipsed lunar disk glowing red and dim low in the eastern sky.

Alaskans will also see the moon rise during the eclipse; in fact, much of western Alaska will see the moon rise while completely immersed in the Earth's shadow.

For Hawaiians, moonrise unfortunately comes just after the end of totality, with the moon gradually ascending the sky and its gradual emergence from the shadow readily visible.

Western Europe and Africa also will get a good view of the eclipse, but at a less convenient time: before dawn on Thursday morning, Feb. 21.

Total triangle

Moreover, this eclipse comes with a rare bonus. The planet Saturn (magnitude +0.2) and the bright bluish star, Regulus (magnitude +1.4) will form a broad triangle with the moon's ruddy disk.

Careful watchers will notice the moon changing its position with respect to the star and planet as it moves eastward through the Earth's shadow.

Saturn's position will also depend somewhat on your location. Seen from North America, the great ringed planet will be 3.5 degrees above and to the left of the moon's center at mid-totality (3:26 Universal time February 21st). At the same moment, Regulus will sit just 2.8 degrees above and to the right of the moon.

Some old-time astronomy buffs may remember from 40 years ago a total lunar eclipse with the moon sitting only about a degree from Spica — a gorgeous celestial tableau! More recently, in 1996, a totally eclipsed moon passed within 2 degrees of Saturn.

But this upcoming double event will be the only one of its kind occurring within the next millennium!
