Note: Theodulf did not seize during the G4–G5 events (Nov 2025, Jan 2026) |
⚠ Max sensitivity ceiling = 57%. Sep 25, Dec 19, Mar 17 were geomagnetically quiet — those clusters are driven by other triggers. Kp is a co-trigger, not a universal predictor. Use alongside barometric pressure and humidity data.
Mitigation Protocol · When Kp Is Elevated
⚠ Moderate Alert · Kp ≥ 4.0 × 2 periods
Heightened Awareness
- No visitors or new people in the home
- Maintain strict feeding / medication schedule
- Quiet environment — minimize arousal events
- Extended grounding time (grass/soil, 20–30 min)
- Verify evening magnesium glycinate dose is not missed
- Log current Kp value in seizure diary
🔴 High Alert · Kp ≥ 5.0
Full Pre-Seizure Protocol
- All Moderate actions plus:
- Administer melatonin (1.5–3 mg, immediate release) that evening
- No grooming, vet appointments, or boarding
- No high-arousal play or exercise
- Rescue medication accessible and confirmed
- Confirm neurologist contact is available
Mechanism · Why geomagnetic storms affect seizure threshold
Geomagnetic storms suppress nocturnal melatonin via cryptochrome-mediated HPA axis activation. Suppressed melatonin lowers the threshold for hippocampal/amygdala seizure discharge propagation. The mitigation strategy targets this pathway directly — melatonin supplementation during storm windows, magnesium (NMDA antagonist) to block calcium flux, and stress minimization to avoid HPA co-activation.
