• Sunday's CME sparked moderate (G2) geomagnetic storming

    A G2 geomagnetic storm is now in progress following CME impact on Earth's magnetic field early on October 2, 2013. The ACE spacecraft detected a solar wind increase to above 600 km/s and the Bz component (IMF) initially tipped sharply south to -19nT.

  • Strong CME impact – G2 Geomagnetic Storm

    Long duration M 1.2 solar flare erupted on March 15, 2013 and launched a Full-Halo Coronal Mass Ejection (CME) toward Earth. It hit Earth’s magnetic field at 06:01 UTC on March 17, 2013 and Geomagnetic K-index of 6 reached threshold on March 17, 2013 at 08:42
