2 bright red circle shaped objects almost jellyfish like

coming home from work, i saw 2 bright red circle almost jelly fish like obejects hovering  in the sky  about 100 or more feet apart from each other traveling from the whittier area heading over pico rivera towards the montebello area. one of the objects the one in the back appeared to drop almost like a ash/ fire debris from it and then vanish,  while the one in the front continued heading west bound towards the montebello area. until it got to far for me to see.   this is the second time i have seen this in about a month period. last time i saw 4 of these objects.
