G1 (Minor) geomagnetic storm underway

G1 (Minor) geomagnetic storm underway

Earth is currently under the influence of a coronal hole high speed solar wind stream (CH HSS) which is causing geomagnetic storming around the poles.K-index of 5 (G1-Minor) threshold was reached at 17:18 UTC today. Area of impact is primarily poleward of 60 degrees Geo

Minor geomagnetic storm in progress, weak negative CH HSS expected

According to the SWPC, the ACE satellite observed a pair of discontinuities in the solar wind field during the past 24 hours. The first discontinuity at 02:35 UTC on December 21 was weak and possibly indicated the arrival of a glancing blow from the December 17th Corona

Two CMEs heading toward Earth, severe geomagnetic storms expected

There are currently two Coronal Mass Ejections (CMEs) heading toward our planet and their combined arrival is expected to spark severe geomagnetic storms.The first one, released by the long duration M4.5 solar flare on September 9, is expected to hit Earth's magneti

Geomagnetic storm reaching G2 – Moderate levels in progress

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

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

As predicted by analysts at the Goddard Space Weather Lab, a coronal mass ejection (CME) hit Earth’s magnetic field at ~03:30 UT on Sept 17th. The impact was not strong. Nevertheless, the arrival of the CME could spark geomagnetic activity around the Arctic Circle.
