A Coronal Mass Ejection (CME) unleashed by solar filament eruption on August 15 started interacting with Earth's magnetic field around 07:00 UTC on August 19 causing, at first, only a minor instability.As the Earth passed through the plasma cloud the effects in

Solar filament eruption on June 4th unleashed a Coronal Mass Ejection (CME) which partially hit Earth's magnetic field at 16:57 UTC on June 7, 2014. The impact sparked minor geomagnetic storming which increased by the morning of June 8th. Geomagnetic K-index of

As forecasted yesterday Coronal Mass Ejection (CME) hit Earth's magnetic field around 03:00 UTC today. That's a second CME impact within 24 hours, and another round of auroras. 

SWPC issued Geomagnetic K-index of 6 (G2 – Moderate) alert at 05:28

Geomagnetic storming sparked by coronal hole high speed stream in progress

Earth is now under the influence of a stronger than expected coronal hole high speed stream (CH HSS). G2 (Moderate) geomagnetic storming has been observed and continued low-level storming is possible over the next 24 hours as Earth remains under the influence of

Sunday's CME sparked moderate (G2) geomagnetic storming

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.

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
