GEOMAGNETIC STORM: A strong geomagnetic storm is in progress as Earth's magnetic field reverberates from a CME strike on July 14th. At first the CME's impact seemed relatively weak, but conditions in the wake of the CME have become stormy. Analysts at the Goddard Space Weather Lab say that satellites in geosynchronous orbit may have been directly exposed to solar wind plasma. Also, Northern Lights have appeared in the United States as far south as California, Utah and Nebraska. Aurora alerts: text, voice.
Brad Goldpaint sends this picture of the auroras reflecting from Sparks Lake in central Oregon:
Meanwhile in the southern hemisphere, the aurora australis has been sighted in New Zealand, Australia, and directly above the South Pole itself.
