6-8 Orange balls of light following each other

At first, assumed they were military helicopters with how the were following each other (line and spacing) No sound, No red blinking lights, appeared to be orange balls. Slow moving, each one would get to the same spot in sky (sundown, sparse cirrus clouds), pause a few seconds, then appeared to move "up", dim and twinkle a bit, then fade out completely. Each "orange ball" respectively did exactly the same once they got to same spot as the first orange ball, until all six were gone. Seen by neighbors also.
