NOAA put a Space Weather Watch in effect until 9/14 due to the combined effects of two separate solar events.  The combination of a CME along with an R3 event have them predicting a possible G3 (Strong) storm on September 13th,

Highest Storm Level Predicted by Day:
Sep 12:  G2 (Moderate)
Sep 13:  G3 (Strong)
Sep 14:  G1 (Minor)

Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.
Possible impacts of this event include:

Induced Currents – Power system voltage irregularities possible, false alarms may be triggered on some protection devices.
Spacecraft – Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.
Navigation – Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.
Radio – HF (high frequency) radio may be intermittent.
Aurora – Aurora may be seen as low as Pennsylvania to Iowa to Oregon.
