While outside i noticed 2 emerald green orbs of light and no sound and not flashing, moved from north east to south they were followed behind by a helicopter that was almost escorting them. it was almost like 1 giant object as the stars behind it dissapeared as they went by. if not for the helicopter me and my kids would have never heard the object. it made my heart almost stop. we watched it until i went out of sight. the helicopter was moving back and forth behind it.
