The stages
Each step is one of Space-Track’s element sets, run through SGP4 and set against the other’s. A stage is raised by one set and confirmed when a later one agrees.
published 10:26 AM UTC
Same plane seen
LEO Express 2’s orbit was found in Object 66687’s plane, 0.022° off, and 2.03 km lower.

Δa is the semi-major axis of the one that moved less the other’s; θ is the angle between the two orbits’ planes. A day later is where the set puts the two 24 hours on, with no further manoeuvre. An exclusion tag on any verdict would keep the pair off the list.
