CANCEL WATCH: Geomagnetic Storm Category G3 Predicted
Original Issue Time: 2016 Oct 13 1329 UTC
Comment: G3 (Strong) geomagnetic storm conditions are no longer evident in available solar wind data. G1 (Minor) geomagnetic storming is likely for the remainder of 14 Oct and the early portion of 15 Oct in response to waning effects of the 09 Oct CME.
Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.
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.
