UFO Sighting in Rohnert Park, California on September 19th 2015 – 7 fire orbs moving togather, but changing formations. then all disappeared

On my way to work at 9:55 pm I witnessed 7 fire orbs floating in the nite sky changing formations but all still moving in the same direction. I pulled over and watched for about 2 mins, tryed to get a video but it didn't come out very clear. I called my dad to tell him to come outside and see them as I turned my car around to get a better view as they moved behind some trees. When I turned back around they had vanished.
