Geomagnetic storm reaching G2 - Moderate in progress

Earth's geomagnetic field is disturbed since early June 7, 2015 as a result of solar sector boundary crossing (SSBC) preceding the negative polarity CH HSS. Geomagnetic storms reaching G2 - Moderate are in progress today.SWPC said SSBC occurred at 01:45 UTC on June

Disturbed geomagnetic field: Brief G2 - Moderate geomagnetic storm

Earth's magnetic field is still disturbed in response to continued presence of a positive polarity coronal hole high speed stream (CH HSS), possibly combined with a transient feature originally expected for May 17. Between 12:30 UTC on May 18 and 12:30 UTC on May 1

Geomagnetic storm reaching G2 - Moderate levels in progress

Geomagnetic storm reaching G2 - Moderate levels is currently in progress due to continued accelerated solar wind speeds and enhanced magnetospheric activity. This activity is attributed to a well connected coronal hole located just south of the solar Equatorial plane, S

Southern pole connected CH HSS causes unsettled to major geomagnetic storms

Southern pole connected coronal hole high speed stream (CH HSS) is causing unsettled to major (G2 - Moderate) geomagnetic storms since April 15, 2015.Geomagnetic K-index of 6 (G2 - Moderate) threshold was reached at 23:27 UTC on April 16, 2015.During the last 12 hours (

Geomagnetic storm reaching G2 Moderate levels in progress

The solar wind environment at the ACE spacecraft displayed two weak transient signatures near 01:00 and 09:00 UTC on April 9, 2015, suggesting the arrival of the April 6 Coronal Mass Ejection (CME) from Region 2320 and a weak coronal hole high speed stream (CH HSS).Wind

Unanticipated CME hit causes G3 - Strong geomagnetic storm

Our planet is still under the influence of coronal hole high speed solar wind speed (CH HSS) which is fueling geomagnetic storming around the poles. Additionally, an unanticipated Coronal Mass Ejection (CME) passed the ACE spacecraft and Earth around 05:30 UTC today

Geomagnetic storm (G1) in progress, severe levels at high latitudes

Solar wind parameters indicated the arrival of the November 7 CME earlier today. At approximately 01:37 UTC, when CME arrived, total field increased from around 10 nT to a maximum of 23 nT at 01:46 UTC. The Bz component increased to +21 nT before briefly going southward

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 reached G2 levels, amazing auroras photographed from ISS

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

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 in progress, M3.0 solar flare from western limb

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

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
