"INFO: CME impact sparks geomagnetic storm"
Space Weather News for August 3, 2010
CME IMPACT: As expected, a coronal mass ejection (CME) hit Earth's
magnetic field on August 3rd. The impact, which occurred around 1730 UT,
sparked a polar geomagnetic storm. At the time that this alert is being
written, sky watchers in Europe as far south as Germany are reporting red
and green Northern Lights. If the storm sustains itself for a few more
hours, people in North America might see a similar display. Sky watchers
in Alaska, Canada, and northern-tier US states such as Wisconsin,
Minnesota and Maine should be alert for auroras.
