The 3 Starlink V2 mini sats still orbit raising seem to have picked up the pace, and may join their v1.5 friends at a 43 degree inclined ~553-559km orbit in around 2 weeks

Confirmed with today's TLE data, 17/21 from Group 6-2 are raising thus far.

Yesterday:

STARLINK-30042, 30051, and 30058 V2 Minis from Group 6-1 have leveled off at 480x476km orbits. At least 17/21 sats from Group 6-2 have begun to orbit raise. Still no TLE update for STARLINK-30096.

8 of the 16 Starlink V2 Mini's raising from Group 6-2 have reached their operational altitude of ~479km, the rest should be there in under a week

Crosspost from launch thread:

Still no SupTLEs for one of the 22 satellites from the Starlink Group 6-4 launch (would be object H in @TSKelso  's list, Starlink number still not known) - suggests that sat has likely failed.  A second sat from the launch, Starlink 30143, also looks to be in trouble.

In their Aug 2021 filing to the FCC, SpaceX said their 43.0 deg inclination shell for the Gen2 system would be at 530 km altitude, but apparently the allowed slop on this is huge, to the point where the number is not very meaningful. Let's look at where they actually are...

Starlinks in Group 5 (V1.5, blue) and Group 6 (V2-Mini, magenta) have been launched to the 43 deg inclination under the Gen2 licence. The ones that seem to have completed orbit raising are in 4 groups at 523, 553, 559 and 561.5 km.

Update:  I understand from SpaceX that the target altitude for the Grp 5/6 sats is 560 km (that may correspond to the 559 km slot in the altitude measurement I use). So the other 3 groups at 523, 553, 561.5 km are still doing orbital plane drift and will end up at 559 later.

Another sat from the troubled Starlink Group 6-1 batch is being prematurely retired; on Sep 15 SpaceX began rapidly lowering the orbit of Starlink 30059 towards reentry

Starlink-2359 reentered near Vancouver at 1837 UTC (11:37 am PDT) Wed Oct 18. It was launched in 2021 and was retired from the constellation on Mar 31.

Starlink-6269, launched on May 4, reentered over Carlsbad, Texas at 2357 UTC Oct 22; it failed around mid-June.

Something odd going on with a group of 6 Starlink sats of disparate ages: all lowered toward reentry around the same time, but then all have started to slightly raise orbit again. Perhaps just some end-of-life testing

I have little experience in satellite orbital changes. Is it possible that they lowered the satellites to let them precess into a slightly different plane? How about to move then slightly ahead before putting them back into their orbit?
