'Blood Moon' Appears Over Eastern Oklahoma
TULSA, Oklahoma - A total lunar eclipse turned the moon a reddish hue Tuesday morning over eastern Oklahoma.
The so-called "blood moon" happens when the earth passes between the sun and the moon, creating a shadow on the moon's surface.
This eclipse between 2 a.m. and 3:30 a.m. marked the beginning of a tetrad, a series of four total lunar eclipses in a row.
The next three total eclipses will occur on October 8, 2014, April 4, 2015, and on September 28, 2015.
