Daily Operational EOP Prediction based upon EAMF forecast for prediction horizon <= 10 days) and AR/LS extrapolation (for prediction horizon

Daily Operational EOP Prediction at 0h and 12hUTC

From EAMF forecast for prediction horizon <= 10 days and extrapolation of an autogressive / harmonic model (LS estimation) for prediction horizon > 10 days

Today prediction from 22 May 2026 (today) at 0hUT

Today prediction from 22 May 2026 (today) at 12hUTC

Predicted values at 0h UTC : MJD / x (mas) / y (mas) / UT1R -TAI (ms) / dX (mas) / dY (mas) / LOD (ms)

Predicted values at 12h UTC : MJD / x (mas) / y (mas) / UT1R -TAI (ms) / dX (mas) / dY (mas) / LOD (ms)

RMS of (prediction at 0hUTC - final C04 value) as a function of the horizon day

Horizon 0 correspond the 'real time' value at 0hUTC given by IERS Bulletin A. Horizon days 1,2,..,10 correspond to EAMF forecasts.
