Louisville, Ky. (WHAS11) - Louisville experienced a total lunar eclipse on April 15, which made the moon appear to have a reddish color.
It's called a blood moon, and it happened between 3 and 4:30 a.m. During the eclipse, the moon turned red as it passed into the earth's shadow, reflecting the shimmers of sung lights and sunset in the atmosphere.
The moon has to be full in order for a total lunar eclipse to occur. The reddening process takes about an hour. The eclipse will happen again in September, and then three more times in six-month intervals ending in September of next year.
