Cees Bassa's 20712C correlates with Russell's UNID of July 26. I fit the following to Russell's obs and Cees's first two passes of observations: 568 X 581 km 1 99569U 20712C 20212.97066404 .00000000 00000-0 00000-0 0 06 2 99569 53.9733 218.7807 0009406 342.9972 17.0709 14.97457034 06 Here are preliminary elements fit to the first set of 20712F observations posted earlier by Cees Bassa: 576 X 577 km 1 99572U 20712F 20212.90888481 .00000000 00000-0 00000-0 0 00 2 99572 54.9459 224.8028 0001000 359.9802 0.1207 14.96862194 03 C and F appear to have last been in very close proximity early on 2020 Jul 21 - around 00:57 UTC, near the northern apex of the orbit, over Europe. Once precise orbits have been determined for all of the objects, we should be able to reconstruct the first two weeks after launch.
