Numerous M-class flares and CMEs off the northwestern limb

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

G1-Minor geomagnetic storm in progress

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

Southern crown coronal hole stirring up geomagnetic storms

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

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

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

Impulsive M1.5 erupts off the east limb, Earth under the influence of CH HSS

An impulsive solar flare measuring M1.5 at its peak time erupted early on December 13, 2014, from a region rotating around the SE limb. The event started at 05:13, peaked at 05:20 and ended at 05:25 UTC.This new region shows a good potential for increased solar activity

G1 (Minor) geomagnetic storm in progress

NOAA/SWPC issued G1 (Minor) geomagnetic storm alert early on December 7 due to the high speed solar wind stream originating from a geoeffective coronal hole in the Sun's southern hemisphere. Geomagnetic K-index of 5 (G1 - Minor) threshold was reached at 01:24 UTC to

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
