This is IGS Opt 5 R/B [40539/15015B].

I observed it yesterday and Mike estimated an orbit of 407 x 414 km,
compared to the 417 x 431 km orbit it had when it was last seen during
the summer of 2021. However, it appears it is quite a bit lower, as
linking your observations with those of mine yesterday shows the orbit
is more like 398 x 406 km.

Here is my TLE estimate:
IGS 5 Opt R/B
1 40539U 15015B   22085.13682183  .00000000  00000-0  95716-3 0    06
2 40539  97.5916 245.4625 0006113  82.8317 336.1181 15.55054854    03
# 20220325.11-20220326.14, 19 measurements, 0.018 deg rms
