Rearrangements in the USA 328 - 331 'train'

In front of the 'train' USA 328 to USA 331 launched last month (see previous posts here and here), things are changing, and objects are being rearranged.  The train is streching out too. It now takes the train almost 6 minutes to pass, and the bright F object is no longer the last trailing object.

On the night of 5/6 July, USA 328 and USA 329 were very close to each other. The image above is a stack of 100 video frames (4 seconds)  showing both objects. The brightness difference of almost 2 magnitudes between (the objects we dubbed) USA 328 and USA 329 was remarkable.

Below is a video of this pass. The footage was made with a WATEC 902H2 Supreme + Samyang 1.4/85 mm lens.  The two objects were some 2 km apart in reality.
