Event date: 2025-12-03
Other systems: HF radio propagation can fade at higher latitudes, and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic lat.)
possible changes in drag affect orbit predictions.
Spacecraft operations: corrective actions to orientation may be required by ground control
Power systems: high-latitude power systems may experience voltage alarms, long-duration storms may cause transformer damage.
