Earth-Event–Linked Modulation in SDO/HMI Global Doppler Velocity during FIFA World Cup Finals An Observational Report Motivated by Adaptive Spacetime Rendering (ASR)

This paper reports an observational time-domain analysis designed to test (without assuminglocal normalization) whether an Earth-local time-rendering factor may transiently deviate duringhigh-information human collective events, using the Sun as an external, quasi-stable oscillator. Motivated by the Adaptive Spacetime Rendering (ASR) framework introduced in Jo, 2026, where the time-rendering factor τ is often normalized to unity at the observer, we here avoidthat normalization and instead treat the observer-side factor as potentially time dependent. Weanalyze Solar Dynamics Observatory / Helioseismic and Magnetic Imager (SDO/HMI) disk-averaged line-of-sight Doppler velocity (45 s cadence) Pesnell et al. , 2012, Scherrer et al. , 2012, Couvidat et al. , 2016 in three windows centered on FIFA World Cup Final match conclusions (2014, 2018, 2022): from T0 −2 h to T0 +1 h. For each final-day window we construct two controlssampled at the same clock-time offsets +3 days and +7 days. After detrending, band-passfiltering (2–5 mHz), and forming the analytic-signal envelope, we quantify post-event modulationbyσrel (∆) ≡ 1 − Afinalpost (∆) medianActrl +3dpost (∆), Actrl +7dpost (∆), Apost (∆) = mediant∈0, ∆ E (t), (1) where E (t) is the envelope and ∆ ∈ 10, 20, 30 min. Across all three finals we find a local-ized post-T0 envelope modulation relative to controls at the 30-min scale: σrel (30 min) ≈ 0. 40 (2014), 0. 30 (2018), and 0. 44 (2022), with the 2022 signal remaining localized under a T0-grid ro-bustness scan. We emphasize that this is an observational report with conservative controls andexplicit limitations; it is intended to provide a reproducible empirical basis for future, separatelydocumented theoretical generalizations.
