GEOMAGNETIC STORM Kp Index is at level 7

***HIGH ALERT***
G
EOMAGNETIC STORM

Kp Index is at level 7
Scale of G3
Strong

Power systems: voltage corrections may be required, false alarms triggered on some protection devices.
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)

Kp Index NOAA 11.09.15 18.00 hrs UTC
