IERS pole still drifting: x=0.211445″, y=0.339610″ — wobble, not a reversal

Lane: ecdoIERS Earth Orientation Centre, Paris Observatory

The International Earth Rotation and Reference Systems Service Rapid Service product finals2000A.daily now carries Bulletin A final polar-motion values through 31 August 2026 (Modified Julian Date 61283): x = 0.211445 arcseconds (σ 0.000092), y = 0.339610 arcseconds (σ 0.000090). The ASCII file on the IERS datacenter was last modified 31 August 2026, 1:15 PM EDT. Those numbers locate Earth’s rotation axis relative to the crust. They are not a geomagnetic reversal and not proof of ECDO. This is a newer dated row than the 27 August snapshot already on this board.

Named place (estimated): IERS Earth Orientation Centre at Paris Observatory. Polar motion is an Earth-orientation measurement, not a reversal, and this pin is not an event epicenter.

The motion of the rotation axis of the Earth relative to the crust is represented by the Earth Orientation Parameter x and y. It has two major components: (i) a free oscillation with period about 435 days (Chandler wobble) and (ii) an annual oscillation forced by the seasonal displacement of air and water masses.

This snapshot uses only the Bulletin A final (type I) polar-motion columns for 31 August 2026. The 1 September 2026 line in the same product is flagged P (prediction) and is not quoted as a measurement.

What this is not

This is not a pole-reversal forecast and not a correction of the 27 August note except to add a later official date. Geomagnetic Kp and the World Magnetic Model remain separate NOAA products. Official Earth-orientation data stays separate from the ECDO hypothesis tracked on this lane.

Why it matters

A new daily final is a geodetic update, not a countdown. Some ECDO talk treats each polar-motion tick as evidence of a coming flip. IERS x and y for 31 August 2026 are where the axis sat that day. ECDO remains a tracked hypothesis, not proven science, and is kept off this official-data note. The 1 September row in the same file is flagged P — prediction — and is not used here.
