Since #23728 95 66  A is in a midnight orbit, it has not been visible in the
northern hemisphere, but I found recently it has already reached the 20 degree
elevation for me.
However, I have not had a clear night since then.
Here is a search orbit, generated by Vec2TLE, assuming reboost end of
November, with time separation from USA 129 near upper operational limit,
decreasing slowly since then (now 227 min.).

Subtract (add?) multiples of 0.01 to 99044.44 to get alternative orbits.
