3 solid lights moving very quickly frightening

three solid orbs of light, dimmer than surrounding stars and moving very quickly in a triangular formation, one leading and two following. we don't have planes that can travel at that speed. silent and very fast. Not blinking, just constant, small round orbs sort of dim amber they slowed a couple of times and regrouped then flew directly away and dimmed out of sight... they flew past the plough constellation.
