GEOMAGNETIC STORM IN PROGRESS
Kp Index is at level 6
Scale of G2
Moderate
Power systems: high-latitude power systems may experience voltage alarms, long-duration storms may cause transformer damage.
Spacecraft operations: corrective actions to orientation may be required by ground control; possible changes in drag affect orbit predictions.
Other systems: HF radio propagation can fade at higher latitudes
