A negative polarity, coronal hole high speed stream (CH HSS) became geoeffective early March 6, 2016, causing an increase in solar wind speeds and an enhanced interplanetary magnetic field. A G1 – Minor geomagnetic storm began at 17:28 UTC, increased to G2 -…
A geomagnetic storm reaching G1 – Minor levels is currently in progress due to the arrival of the co-rotating interaction region (CIR) associated with coronal hole 55. The proton flux might reach S1 – Minor levels in the period between February 16 and 18 due to the…
Prolonged effects of a partial-halo CME impact, produced by the filament eruption just of center disk late on January 14, 2016, is causing a G1 Minor geomagnetic storm on January 20, 2016. The CME reached our planet just before 21:00 UTC on January 18. Geomagnetic…
An active region currently positioned behind the northeast limb erupted with two M-class solar flares by 10:19 UTC on December 21, 2015. The first event started at 00:52, peaked at 01:03 as M2.8 and ended at 01:11 UTC. The second event started at 10:09, peaked at…
A halo Coronal Mass Ejection (CME) generated by December 16th C6.6 solar flare has reached our planet on December 19 causing enhanced solar wind conditions, prolonged period of the southward magnetic field and planetary geomagnetic storms reaching G2 Moderate…
Two solar filaments erupted from the SW quadrant of the Sun late November 15 and early November 16 producing a Coronal Mass Ejections (CMEs) that arrived at Earth at 20:10 UTC on November 18. A G1 – Minor geomagnetic storm is currently in progress. This, combined…
Coronal Mass Ejection (CME) unleashed by a long duration M3.7 solar flare on November 4 reached our planet at 18:25 UTC on November 6, almost a full day earlier than it was expected. An enhanced magnetic field, coupled with winds speeds approaching 700 km/s have…
Swedish media is reporting air traffic problems due to "solar storm" interfering with air traffic control radar systems during the afternoon of November 4, 2015. It is unclear, however, whether they meant the Solar Radiation Storm or Geomagnetic Storm, two…

Geomagnetic storm reaching G3 Strong levels is currently in progress as a result of Coronal Mass Ejection (CME) impact on top of Coronal Hole High Speed Stream (CH HSS) influence.The CME, produced by September 18th C-class solar flare, reached our planet at 06:05 UTC on
Our planet's magnetic shield is again under stress today with brief G3 Strong geomagnetic storm levels reached around 09:00 UTC. The storms began on September 7 with positive polarity coronal hole reaching geoeffective position and an impact of plasma filament
