> A CME HIT EARTH'S MAGNETIC FIELD TODAY: Minor G1-class geomagnetic storms are underway on Sept. 17th following the predicted arrival of a CME. The strike was, at first, seemingly weak and inconsequential. Now, however, Earth is passing through the CME's magnetized wake and experiencing geomagnetic disturbances. If storm conditions persist, auroras could become visible in northern-tier US states after nightfall. Full story @ Spaceweather.com.
