CME IMPACT: As expected, a coronal mass ejection (CME) hit Earth’s magnetic field on Sept. 3rd at approximately 1200 UT (5 am PDT). The impact induced measurable ground currents in the soil of northern Scandinavia and sparked bright auroras around the Arctic Circle. At the time this alert is being issued, a moderately strong (Kp=6) geomagnetic storm is underway. Check http://spaceweather.com for photos and updates.
STORM ALERTS: Subscribers to our Space Weather Alert service were alerted by phone when the CME hit and when the subsequent storm began. You can sign up for alerts at http://spaceweathertext.com (text) or http://spaceweatherphone.com (voice).
One of these days, the CME will cause that big EMP.
Those of you in northern latitudes might want to watch for auroras tonight.
