Three green UFOs photographed over Grapevine, California

On December 1, 2014, during sunset, a person has taken a photo of sky while he was near Grapevine, California. Later, he noticed three green luminous UFO forming a triangle!

Witness statement:

I was taking a photo of the sunset at the base of the Grapevine outside of Bakersfield, CA and it wasn't until I reviewed the photo later that I noticed three bright green lights forming a triangle in the sky. While I took the photo I didn't hear anything or see anything only noticed the object later.
