Major X1.0 solar flare erupts from AR 3110
A major solar flare, measuring X1.0 at its peak at 20:25 UTC, erupted on October 2, 2022, from Active Region 3110. The event started at 19:53 and ended at 20:34 UTC.
M8.7 solar flare erupts from AR 3110
A strong solar flare, measuring M8.7 at its peak, erupted from Active Region 3110 at 02:21 UTC on October 2, 2022. The event started at 02:08 and ended at 02:21 UTC. The event comes several hours after impulsive M5.8 from the same region at 20:10 UTC on October 1.
Strong M7.9 solar flare erupts from AR 3098
A strong M7.9 solar flare erupted from Active Region 3098 at 09:49 UTC on September 16, 2022. The event started 09:44 and ended at 09:56 UTC.
Major farside coronal mass ejection (CME) and radiation storm
A spectacular full-halo coronal mass ejection (CME) erupted on the farside of the Sun on September 5, 2022. The source is Active Region 3088, which is expected to return to Earth’s view in about a week.
Strong positive polarity CH HSS sparks G2 – Moderate geomagnetic storm
A strong positive polarity coronal hole high speed stream (CH HSS) sparked a G2 – Moderate geomagnetic storm on September 4, 2022. G1-Minor storms continued into September 5. An additional enhancement is possible by midday today due to the arrival of CME produced on September 2.
Three M-class solar flares – M2.1, M7.2 and M5.3 erupt from AR 3089
Active Region 3089 (Beta) produced three M-class solar flares on August 26, 2022 – M2.1 at 10:55 UTC, M7.2 at 12:14 UTC, and M5.3 at 12:31 UTC.
G3 – Strong geomagnetic storm watch
A series of coronal mass ejections (CMEs) produced on August 14 and 15, 2022 are expected to couple with a recurrent, negative polarity coronal hole high speed stream (CH HSS), sparking G1 – Minor to G3 – Strong geomagnetic storming through August 19.
Multiple Earth-directed CMEs, G2 – Moderate geomagnetic storm predicted for August 18
A G2 – Moderate geomagnetic storm watch is in effect for August 18, 2022, as a result of CME activity on August 14 and 15 coupled with a recurrent, negative polarity CH HSS.
Positive polarity coronal hole high speed solar stream sparks G2 – Moderate geomagnetic storming
Earth is under the influence of multiple positive polarity coronal hole high speed solar streams (CH HSS), triggering G2 – Moderate geomagnetic storming.
CME reaches Earth, sparking G1 – Minor geomagnetic storm
Coronal mass ejection (CME) produced by a long-duration C5.6 solar flare on July 21, 2022, hit Earth’s magnetic field at 02:59 UTC on July 23, 2022, sparking G1 – Minor geomagnetic storm.
