ANOTHER CME:\u00a0<\/strong>Yesterday, Aug. 17th, active sunspot AR3078 produced a rapid-fire pair of M-class solar flares (M1+M2). The double blast hurled this CME into space:<\/p>\n\n\n\n Although the bulk of the CME is directed south of the sun-Earth line, there appears to be an Earth-directed component. A faint halo suggests that a fraction of the cloud is heading our way. If so, it should arrive on Aug. 20th. Stay tuned for further analysis of this event.<\/p>\n\n\n\n Space Weather Message Code: WATA50 WATCH: Geomagnetic Storm Category G3 Predicted<\/p>\n\n\n\n Highest Storm Level Predicted by Day: THIS SUPERSEDES ANY\/ALL PRIOR WATCHES IN EFFECT<\/p>\n\n\n\n NOAA Space Weather Scale descriptions can be found at 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.
Aurora – Aurora may be seen as low as Pennsylvania to Iowa to Oregon.<\/p>\n","protected":false},"excerpt":{"rendered":"
