I'm having trouble wrapping my head around one aspect of the video DaveG posted in
post 61 above. Some of the satellites appear to be moving at different speeds. A notable example is at
3:18 in -- click here for cued link. Of the three satellites circled in this picture, two of them appear to be pulling away from the third at higher speed.

My undersdtanding is that the whole lot of them are at essentially the same altitude, and so should be moving at essentially the same speed. Might the slower satellite be something other than Starlink, at a higher/slower orbit? But if so, it seems a striking coincidence that it would flare at the same time, unless the difference in geometry is less than I am imagining. Or is it a perspective effect with the slower satellite moving at more of an angle away from the camera?
It's not vital, and these "raetrack" UFOs are pretty clearly established as Starlink flares, but I am curious and if anybody has an answer I'd appreciate it.
