The Skykraft 4 satellites from the TRACERS launch have now been cataloged in 590 km orbits; however the Space Force orbit data for SKYKRAFT 4B (64896) are spurious - they show it in a geotransfer orbit that must actually belong to an Ariane stage fragment

Chinese civilian comms satellite Zhongxing-9C launched by Chang Zheng 3B from Xichang at 1237 UTC Jun 20. Two objects tracked, one in 241 x 35802 km x 27.5 deg geotransfer, other (object A) in unexpected 218 x 12430 km x 26.7 deg orbit. Too early to interpret this anomaly.

There are rumors that Indian navigation satellite #NVS-02 is in trouble. After being placed into the geotransfer orbit, it was supposed to perform a series of orbit-raising burns to reach its planned geostationary orbit. However, observations indicate that no orbit-raising has occurred so far. 🥹
