Four, red white blue and green, glowing objects flew overhead. Did not make a sound.Me and my girlfriend were in my backyard, sitting on our patio furniture facing west. I first observed at a distance, facing west, a white sphere. Then right behind it I saw green sphere, then red then blue. I first I thought the white sphere was the light from a plane or helicopter. This is common where we live. However, as the objects got closer, I was expecting a sound but never heard any. I kept looking at them because had never seen such glowing colored lights on any aircraft before. They were not blinking. More resembling glowing balloons. Were moving way too fast to be just drifting. I caught on video from my gf's cell but was hard to make out. Only some of the green glowing object could be seen. It appeared to me that they were not connected together, but more like flying in a group, with no visible pattern that I could tell. They flew overhead, not making any sound, and continued into the distance to the east keeping the same pace.((NUFORC Note: Source of the report elects to remain totally anonymous; provides little contact information.
