Looked like a single star or satellite flying overhead.

Last night I was sitting outside waiting for Starlink. It was supposed to pass over Duarte California at 9:22 pm coming from Northwest to East. At 9:12 pm, I saw an individual object coming from the West and heading slightly Southeast. As the object got closer to me, I could see a white light behind it. That light was very bright white emitting in a large fan like pattern. I know Perseid is here, but unlike a meteor, this object was moving fairly slow, and it was visible to me for a couple of minutes. This was very visible over the Los Angeles area. Surely, I can't be the only person to have seen this. I took a short video of it with my camera phone. I don't know why, but the video shows the object as blue, but it was bright white. And it doesn't really show the large fan like light that it was emitting behind it. FYI, the horizontal white line in the video is just the telephone pole wires. It looked like a comet to me. Please let me know if you determine what this was.
