Three red lights in the sky in a triangular formation. coming from the north east, it was flying it seemed quiet. like it wasn't making noise but it was too far away to be sure. the lights stayed in the triangular formation seeming to shift with different angles a triangle would make as it shifted but between the lights, there was just sky. they were pretty far apart, as though the object was pretty large. shortly after i noticed two police helicopters appeared over the horizon speeding towards the lights chasing them east towards palomar mountain. the lights flew over the mountain and disappeared with the police helicopters following after.
