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.
