Saw what I thought was a satellite, but it stopped. Moved around then remained stationary. Got my camera and the video is really weird

I like to watch Seatac air traffic from my deck. About 2 am I was sitting out there looking at clouds and a light caught my eye WAY up high. Moving at a pace like an international flight, west to east. But it was too high to be commercial jet so thought it was a satellite. Until it stopped. It kind of moved around a bit before becoming stationary. Weather balloon? Are they lit up and look like stars? Got my camera, iPhone 14pro plus and started recording. Saw a flash to the right of it, which was really odd, but nothing else interesting. Looked back at the video to see if the flash showed up and zoomed in a bit and oh man. I could see more flashes around it. And it looks like the orb is flashing, or is emitting energy or something. It was just weird then really started doing flashy stuff (you’ll see) that’s freaking not normal. No clue what it is, but it’s really weird. Saw something similar the end of June. Thought it was one of the planets to the west, but it was too bright. Decided it was a jet coming in from the ocean. It just stayed there, so I thought damn, it’s way out there. Then it turned like it should, I could see the red lights on the left side. Ok good. It’s a jet. but it just stopped. Huh? Then it traveled rather slowly from west to east. From just above the horizon to almost overhead. Then stopped. Looked like it moved around like in a square but then thought my eyes were tricking me. It just sat there. I watched it for about 20 minutes then went inside thinking “that was not normal”.
