Daily Minimum Dst Ring-Current Evolution Curve (Kyoto WDC, nT)
Note: More negative Dst values indicate stronger equatorial ring-current intensification. Missing hours remain uninterpolated.
✦ Act I · Solar Flare & Coronal Mass Ejection
① Solar Eruption Dynamics
Active region AR 4099 fired multiple M/X flares in late May 2025, driving Dst to −119 nT on June 1 followed by a stepped multi-day recovery phase.
✦ Act II · Magnetospheric Compression & Infrastructure
② Infrastructure Telemetry
High-latitude ionospheric Joule heating caused HF scintillation across Alaska and Scandinavia while commercial satellites performed routine attitude adjustments.
✦ Act III · Terrestrial Bio-Rhythm Resonance
③ Biological Resonance
Demonstrates how consistent dark-room sleep hygiene and cutting evening blue light shield neuro-endocrine melatonin rhythms from moderate geomagnetic fluctuations.
