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
Plasma cloud unleashed by M-class solar flare on August 22 reached our planed early Wednesday, August 27. Wind speeds increased from near 280 km/s to 340 km/s while density remained primarily between 5-10 p/cc (protons per cubic centimeter).Active to minor storm (G1) co
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
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 storm sparked by a combination of CMEs from last couple of days is now subsiding. We might still see uptick today but it will most likely remain below G1 levels.At 10:57 UTC on April 20, a 24 nT geomagnetic sudden impulse (interplanet
During the late hours of April 11 the Interplanetary Magnetic Field (IMF) tipped south and opened a crack in Earth's magnetosphere. Our planet is now under the influence of coronal hole high speed stream (CH HSS). CH HSS effects are expected to begin subsiding
A geomagnetic sudden impulse, indicating the arrival of the March 23 CME, was observed at the Hartland magnetometer (23 nT) at 20:09 UTC on March 25.
The geomagnetic field is expected to be at unsettled to active levels (below G1-Minor) early on March 26 as CME
