A several degree long solar filament south of the Region 2741 disappeared by approximately 15:14 UTC on May 13, 2019. Initial analysis suggests an Earth-directed component is likely with this Coronal Mass Ejection (CME). This is the fifth Earth-directed CME since…
G3 Strong geomagnetic storm levels associated with the passage of slow-moving August 20th Coronal Mass Ejection were observed early August 26, 2018. A faint and slow-moving CME was first seen in LASCO coronagraph imagery at approximately 22:00 UTC on August 20. The…
A recurrent, polar-connected, positive-polarity coronal hole is affecting our planet since September 27. G1 – Minor geomagnetic storm levels were reached at 08:48 UTC on September 27, followed by G2 – Moderate levels at 20:24 UTC and then increased to G3 – Strong…
A Coronal Mass Ejection (CME) produced by the X9.3 solar flare on September 6, 2017, reached our planet at 23:04 UTC on September 7, 2017, a full day earlier than it was expected. G3 – Strong geomagnetic storming started 23:25 and increased to G4 – Severe at 23:50…
An asymmetric full halo Coronal Mass Ejection (CME) produced by the M5.5 solar flare at 20:33 UTC on September 4, 2017 is traveling toward Earth and is expected to arrive late on September 6. G3 – Strong geomagnetic storm watch is in effect for September 6 and 7….
A coronal mass ejection (CME) produced during the early UTC hours of May 23, 2017 hit Earth's magnetic field at 15:36 UTC on May 27, more than 24 hours after it was expected. Although the solar wind speed is relatively slow, the embedded magnetic field had a…
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…
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,…
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…

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
