Public Magnetometer Bounds on RMFD Scalar Gravitational-Wave Backgrounds: A QMU Proxy Analysis of INTERMAGNET Storm-Time Data

This paper presents an initial public-data environmental background study for the Rotating Magnetic Field Detector (RMFD) scalar gravitational-wave program developed within the Aether Physics Model (APM) and Quantum Measurement Units (QMU). Second-resolution geomagnetic observatory data from the INTERMAGNET network are analyzed for both a geomagnetically quiet interval (2024 January 15) and the major geomagnetic storm interval of 2024 May 10. The study uses distributed public magnetometer stations as a first-generation environmental proxy for future RMFD scalar-channel detector arrays. The principal environmental observable is the temporal magnetic variationdBₜₒₜ/dt,which represents the dominant background contribution entering the RMFD pickup-coil voltage chain. Quiet-day temporal magnetic backgrounds are found to occupy the approximate range10⁻¹¹--10⁻¹⁰\ T/s,while storm-time conditions increase the background scale to approximately10⁻¹⁰--10⁻⁹\ T/s. Cross-station Pearson correlations remain modest even during intense geomagnetic activity, with representative correlations satisfyingCᵢⱼ0.33.These results demonstrate that ordinary geomagnetic disturbances are structured but not globally phase-coherent across continental baselines, preserving the discriminating power of coincidence filtering for future RMFD scalar-wave searches. Power spectral density analysis further identifies a broad storm-time enhancement structure in the approximate frequency range10⁻²--10⁻¹\ Hz,providing an initial detector-design constraint for RMFD filtering and transient coincidence optimization. The study also motivates future co-location of RMFD systems with broadband seismographs in order to discriminate candidate scalar-channel events from seismic-magnetic coupling processes including piezomagnetic and magnetotelluric effects. No scalar gravitational-wave detection is claimed. Instead, the work establishes empirical environmental bounds, develops coincidence-discrimination methodology, characterizes storm-time magnetic spectral structure, and defines a practical experimental framework for future dedicated RMFD scalar gravitational-wave searches using distributed synchronized detector arrays. The paper transitions the RMFD scalar-wave program from theoretical detector formulation toward experimentally testable environmental characterization and statistical search methodology.
