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
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 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 (

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
The strongest geomagnetic storm of the current solar cycle (Solar Cycle 24) reached G4 Severe levels (Kp=8) on March 17, 2015 and sparked spectacular auroras in both hemispheres of our planet. The event was identified as the combined effects of CMEs which erupted on Mar
A sequence of events led to an Earth-directed asymmetric halo CME on March 15, 2015. The events began with a 14 degree long filament eruption, centered near S24W38, lifting off between 00:45 to 02:00 UTC. This was followed by C2.4 flare at 00:41 UTC and a long duration
Solar activity reached moderate levels today when Region 2290 (N22W84, Hsx/Alpha) produced a pair of M1 (R1-Minor) flares at 06:39 (M1.0) and 09:48 UTC (M1.1). This region also produced numerous low and mid-level C-class flares over the last 24 hours.Numerous Coronal Ma
A G1-Minor geomagnetic storm is currently in progress due to the influence of a recurrent negative polarity coronal hole high speed stream (CH HSS). Geomagnetic K-index of 5 (G1) threshold was reached at 02:31 UTC on February 24, 2015. Area of impact is primarily polewa
Earth is currently under the influence of a high speed solar wind speed, originating in negative polarity southern crown coronal hole, which is causing periods of geomagnetic storming on our planet.Solar wind readings indicated a co-rotating interaction region (CIR) whi
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
