Multi-colored blinking lights in western sky not moving. After 15 minutes disapeared.Saw object over Etters, PA in Western Sky. Could on see colors blinking Red,Green, Blue and White lights. Could only see the lights blinking for about15 minutes. While seeing object it appeared not to move. After about 15 minutes the object disapeared from sky. While watching a smaller white blinking light moved quickly from south to north. If this was a plane we have never seen one move so fast. Only a few seconds and small white blink light disapeared.
