A recurrent, negative polarity coronal hole high speed stream (CH HSS) has hit Earth's magnetic field causing geomagnetic storms on June 5, 2016. A G2 (Moderate) geomagnetic storm watch is currently in effect. This same CH HSS has affected Earth on May 8 with…
Enhanced solar wind conditions have fueled elevated geomagnetic field activity early May 2, 2016. Geomagnetic storms reaching G2 – Moderate levels have been observed. Geomagnetic K-index of 5 (G1 – Minor geomagnetic storm) threshold was first reached at 00:37 UTC on…
Our planet is passing through a stream of fast-moving, negative polarity solar wind. Geomagnetic storming reached G1 – Minor levels at 17:24 UTC. A G2 – Moderate warning is in effect for the rest of the UTC day. This is a recurrent CH HSS, responsible for G3 -…
After strong G3 geomagnetic storm on March 6 and 7, solar wind parameters increased again around 04:00 UTC on March 11. The cause is most likely a Coronal Mass Ejection (CME) from March 6. Interplanetary magnetic field (IMF) total field (Bt) valuese steadly…
The December 28th coronal mass ejection (CME) produced by the long duration M1.8 solar flare passed the ACE spacecraft at 00:02 UTC on December 31 and reached our planet at 00:51 UTC. Geomagnetic K-index of 4 threshold was reached at 01:05 UTC. The impact is…
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…
Geomagnetic storm reaching G2 – Moderate levels is currently in progress due to continuous influence from a positive polarity coronal hole. This influence will decrease over the next couple of days, however, the Coronal Mass Ejection (CME) associated with the M3.9…
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…
Our planet is under the influence of positive polarity coronal hole today which is causing enhanced geomagnetic conditions. Geomagnetic K-index of 6 (G2-Moderate geomagnetic storm) threshold was first reached at 05:17 UTC today. Geomagnetic K-index of 7 (G3 – Strong…
