started with 2 distinct stars that caught my attention near each other, same brightness. suddenly a 3rd appeared making a perfect triangle. i said out loud “it’s a triangle of stars!” since i thought i just didn’t see the 3rd at first glance. then that one disappears, as the second starts to disappear the witness sees that one leave, then the third finally vanished. no movement no flashes, just faded away one at a time
