Southern Colorado will be able to see the first eclipse of the year early Tuesday morning.

It's the first in a series of four total lunar eclipses. It's called a Blood Moon because the moon is expected to turn a reddish hue.

The reddish color is the result of indirect sunlight that manages to reach the moon to illuminate it. Most of blue light is filtered as light passes through the Earth's atmosphere, resulting in the reddish color.

NASA says the eclipse will start as a partial eclipse at 11:58 p.m. Monday (1:58 a.m. ET). The total eclipse is expected to last from 1:07 a.m. to 2:25 a.m. MT ( 3:07 a.m. to 4:25 a.m. ET).

This total eclipse is the first of four total lunar eclipses, known as a tetrad. The next three will be Oct. 8, 2014, April 4, 2015 and Sept. 28, 2015.

This will be the second of eight tetrads this century, with the last one occurring in 2004 and the next in 2032.
