Mean altitude from the mean motion of each set of elements Space-Track published for STARLINK-34343 (64157). Dots in red are the sets from the detector’s step on; the band is the time shown.

Where it was at 7:30 PM UTC

The orbit STARLINK-34343 was on at the time shown: one orbit from its last set of elements before the event (grey) and one from its first set after it (red). The point is where the set before put it then, 560 km up. Follow it on the live map now. The live map plays back the past 7 days, so this instant is beyond it.

Why it is shown

  • What the detector saw: the mean altitude stepped up by about 13.1 km between the sets of Mar 30, 2026, 9:21 AM and Mar 30, 2026, 5:23 PM UTC; the perigee moved +430 m, the apogee +25.7 km and the inclination +0.0205°.
  • The step held over the 4 sets after it, at 253.6 times the scatter of the parent’s own record.
  • How it was confirmed: by an agency’s notice.
  • The time shown: March 29, 2026, 7:30 PM UTC ± 10 min, reported by the US Space Force’s notice (S4S).
  • The detector’s own estimate: between Mar 30, 2026, 9:21 AM and Mar 30, 2026, 5:23 PM UTC.

Reported by:

The detector’s own reasons, as it wrote them:

  • a public notice names the object: "U.S. Space Forces-Space (S4S) confirms the anomalous debris causing event of Starlink-34343 (#64157, 2025-112M) in LEO, with the event likely occurring on 29 March 26 (JDay 088) at approximately 19:30z (UTC)." The archive's copy of 2026-03-31 11:29 UTC carries no such announcement.
  • the step was read as a manoeuvre from the object's own record; the catalogue says otherwise
  • confirmed 10.3 days after the step
