Total lunar eclipse coming to North, South American sky April 15
By Marcus Hondro
If you live in the North and South American regions then expect a total lunar eclipse to come your way in the wee hours or April 15. Safe to view with the naked eye, if there's a clear sky you'll see the moon in various shades of red and orange.
NASA reports that the eclipse will start out at 1:58 a.m. E.T. as a partial eclipse and move into its total eclipse phase at 3:07 a.m., lasting until 4:25 a.m.
The phenomenon known as a lunar eclipse takes place when the Earth passes between the sun and moon and casts a shadow on the moon. Sunlight getting by the Earth will brighten the surface of the moon and the orange and red hues are seen.
There will in fact be four total lunar eclipses in the next few months, this being the first and the fourth and final will come on Sept. 28, 2015. When such a grouping of four total lunar eclipses occurs over a relatively short period of time it is called a tetrad. The last tetrad occurred in 2004 and the next won't be along until 2032.
