I agree with Dr.Kelso that the Mayak's tetrahedron reflecting surface has not been deployed yet (as of epoch 17206.1). In available TLEs from space-track.org for all objects of the launch 2017-042 without proper names Bstars are like and don't increase significantly (an order of magnitude or more) from one elset to another (about 10^(-4)). The exceptions are 1) one elset for OBJECT V / 42844, epoch 17203.855 (drag term is about 10^(-2)), derivative of mean motion also increases significantly (2 orders), but next elsets show that those parameters return to normal values. 2) in one elset for OBJECT C / 42827, epoch 17204.196 mean-motion-dot decreases, but then also its value returns back. TLEs for OBJECT F / 42830 are ordinary and doesn't show even that. For example, InflateSail's drag term is of order 10^(-2) and higher for all available TLEs.

Heavens Above shows it as 42830/OBJECT F, but if this is correct, the deployment has not yet occurred, since there is no differential motion relative to other objects in relative proximity. - TS > > Dr. T.S.
