Remember a sphere shape of pale orange, yellow color just hovering over the city.

I was only 8 when on my way in a station wagon to a church play or musical when going down the freeway on my upper right looking over the city I saw this sphere shape of pale orange, yellow appeared in the night sky. I hesitated at first and wanted to say something, but nobody would beleive me, so I watched it myself as it would ever so slightly move the same direction as the car and suddenly stop. It just dissapeared after one blink.
