Five or six hovering lights formed into a triangle in the sky in Santa Rosa, California.My girlfriend and I were driving and came into the intersection of College Ave and Humboldt in Santa Rosa, CA, and noticed some bright lights in the sky. It was 10:45 PM. I felt so elated that I called a friend and the cell phone call recorded the time.At first, due to all the light in the intersection, we did not think much of it. As we drove closer and came into a darker area we noticed five and six bright lights formed into a triangle shape in the sky (we were surrounded by trees and, therefore, the visibility was slightly impaired; nevertheless, we could clearly see the triangle formation) .They were slightly swerving into each other but essentially maintained the triangle shape. I asked my girlfriend to stop the car and I got out to get a clearer look at this unusual phenomenon.As I stood there, all of the bright points of light disappeared, except one. They zoomed out at an unimaginable speed leaving no trace whatsoever. The bright point of light which remained did so for another 20-30 seconds, and then slightly dimmed and suddenly it was gone. The color of these lights was a blend of red and orange and they were very bright relative to the surrounding stars.These bright lights might have been hovering at 500 feet or more; it was hard to tell the exact altitude and distance, but they were near enough for us to see what was taking place.The two of us were pretty baffled and amazed but we were convinced that we had witnessed a UFO, and I employ this term in the strict sense of the word as in Unidentified Flying Object.
