1 sphere like round firework. Still. Turned into 3 spheres. No sound until deep hum. No movement @1st. Then 3 from NW to SE.

It looked like a stationary firework display/like a patterned ball.  But not moving or arc-ing. I thought someone had put up some sort of display on a tower but there is no tower over there.  I ran in for the phone/camera.  Then the huge ball that was like a frozen firework started moving up, then forward, this direction.  I kept trying to get photo but it wasn’t happening.  Then it was 3 round lights, 3-D, like almost a plane formation with port and starboard but also front , triangular like a plane, but still these round patterned globes it got closer, lower, no noise until a very low bass hum, not like an engine.  Impossibly low in sky.  Still these round 3-D static firework-like globes.  Then past where I could see.  Nothing wrong with my eyes/I kept looking to see if there were auras around street lights.  Nothing.
Freaked. Heart-pounding experience.
