Earth is currently under the influence of a high speed solar wind stream originating in large southern coronal hole. Although the bulk of this stream is headed south of our planet, we have already experienced severe geomagnetic storm periods at high latitudes.Geomagneti
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
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
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
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
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
A partial halo Coronal Mass Ejection (CME) was generated by major X1.6 solar flare on November 7, 2014.WSA/ENLIL modeling of the event shows a partially Earth-directed component that is expected to impact the geomagnetic field early to midday on November 10 causing acti
For the 5th day in a row a crack in the Earth's magnetosphere is allowing solar wind to reach Earth. Although a full geomagnetic storm is not required to generate auroras at this time of the year, coronal hole effects and multiple solar sector changes currently affe
The Earth's magnetic field got disturbed in response to the arrival of the September 10 halo CME caused by X1.6 solar flare. Magnetometers around the world recorded a Geomagnetic Sudden Impulse at 15:55 UTC which signaled the arrival of the CME at
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
