Strange 6-8 Light Ball UFOs over Monrovia

Story by Pokebub22: In school, my friends and I were playing on the swings and then we saw these strange balls of light flying really up high above us. There were about 6 to 8 of them. They were forming a V and they kept on blinking. It happened in 2012. What do you think it was? Comment and comment on the Encounters page so I can make a new post about any encounter. ~Pokebub22
