STARLINK GROUP G10-13 was launched october 30th, 2024 at 21:10 U.T. from Florida with 23 Starlink v2 mini satellites on board... less than a day later they flew over the swiss Alps , about half an hour after sunset, in twilight sky. Normally you would not be able to see them with this bright sky but because the Sun was in the same direction they were reflecting much more sunlight and therefore appeared brighter than normally and became visible to the naked eye... as they climbed high and flew over Sion Switzerland the sky was already a little bit darker and they were nicely seen in their typical blue colour - and 2 airplanes just happened to cross its path, giving a stunning view... moments later one of the satellites did a bright flare... and as the entire train was flying towards the southeast they were supposed to dim beyond the limit of visibility but instead they brightened again and flared quite a lot , so they were still visible despite the distance and low altitude.

Apparently if you are in the precise axis Sun - satellite train - observer they can flare as they reflect sunlight very brightly.
