A G3 – Strong geomagnetic storm conditions were observed beginning 05:59 UTC on May 8, 2016. G2 – Moderate to G3 – Strong geomagnetic storm conditions are expected through the rest of the day and possibly into May 9 and 10. This activity is caused by a recurrent,…
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…
Earth is under the influence of negative polarity coronal hole high speed stream (CH HSS) since late April 12, 2016. This is causing isolated periods of G1 – Minor geomagnetic storming. Geomagnetic K-index of 5 (G1 – Minor geomagnetic storm) threshold was first…
A geomagnetic storm reaching G1 – Minor levels is currently in progress as Earth enters a stream of positive polarity high-speed solar wind. Geomagnetic K-index of 5 (G1 – Minor geomagnetic storm) threshold was reached at 20:40 UTC on April 7: Space Weather Message…
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 -…
A new round of geomagnetic storming is in progress on March 15, 2016. Solar wind parameters are enhanced since late March 14 due to the onset of a negative polarity coronal hole high speed stream (CH HSS) and are expected to remain like that through March 16….
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…
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…
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…
