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
GEOMAGNETIC STORM IN PROGRESS – Kp Index is at level 5

GEOMAGNETIC STORM IN PROGRESS
Kp Index is at level 5
Scale of G1
Minor
Power systems: weak power grid fluctuations can occur.
Spacecraft operations: minor impact on satellite operations possible.
Other systems: migratory animals are affected at this and higher levels
GEOMAGNETIC STORM IN PROGRESS – Kp Index is at level 7

GEOMAGNETIC STORM IN PROGRESS
Kp Index is at level 7
Scale of G3
Spacecraft operations: surface charging may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems.
Other systems: Intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent, and aurora has been seen as low as Illinois and Oregon
(typically 50° geomagnetic lat)
