Strong M9.4 solar flare erupts from Region 3889, CME produced
A strong solar flare measuring M9.4 erupted from Active Region 3889 at 12:06 UTC on November 10, 2024. The event started at 11:51 and ended at 12:14 UTC.
Long-duration M7.6 solar flare erupts from Region 3842
A long-duration solar flare measuring M7.6 erupted from Active Region 3842 at 23:59 UTC on September 30, 2024. A coronal mass ejection (CME) was not produced during this event but Earth-directed CMEs are possible from this region in the days ahead as it continues evolving and moving into a more geoeffective position.
Long-duration M5.5 solar flare erupts from southeast limb, producing large CME
A long-duration solar flare measuring M5.5 erupted from an emerging region on the southeast limb of the Sun at 13:22 UTC on September 1, 2024. The region was numbered 3813 on September 2.
Multiple Earth-directed CMEs, significant geomagnetic storming possible
Solar activity was at very high levels over the past 24 hours, with a series of moderate to strong solar flares, including an M9.9 flare on July 28 with an Earth-directed component. This, coupled with the cannibal CME expected to arrive late on July 29 into July 30, suggests significant geomagnetic storming is possible, potentially in the range of G3 – Strong or even G4 – Severe on July 30.
Two Earth-directed CMEs, G2 – Moderate geomagnetic storm watch in effect
Two Earth-directed coronal mass ejections (CME) were produced over the past 3 days. The estimated time of arrival to Earth is late July 23 to midday July 24, 2024. A G2 – Moderate geomagnetic storm watch is in effect.
Old region 3664 returns with M9.3 solar flare
Old region 3664/3697 — the source of multiple Earth-directed CMEs and G5 – Extreme geomagnetic storming in May, has returned to Earth-view with a strong M9.3 solar flare at 13:01 UTC on June 23, 2024. The region is now numbered 3723. The event started at 12:51 and ended at 13:11 UTC.
Strong solar radiation storm in progress after M9.7 solar flare produced large CME
A strong, long-duration solar flare measuring M9.7 erupted from Active Region 3697 at 01:49 UTC on June 8, 2024. The event started at 01:23 and ended at 02:19 UTC, producing a strong CME. Shortly after, solar radiation storming began on Earth, reaching the S3 – Strong threshold at 08:00 UTC.
Long-duration M7.3 solar flare produces possible Earth-directed CME
A long-duration M7.3 solar flare was observed on June 1, 2024, peaking at 19:39 UTC. This event, originating from Region 3697, produced an asymmetric coronal mass ejection (CME), with a possible Earth-directed component, according to SWPC.
M9.1 solar flare erupts from geoeffective Region 3663
A very strong solar flare measuring M9.1 erupted from Active Region 3663 at 06:19 UTC on May 4, 2024. The event started at 06:02 and ended at 06:30 UTC. This is the 6th and the strongest M-class solar flare since X1.6 on May 3.
Long-duration M9.4 solar flare erupts from Region 3615
A long-duration solar flare measuring M9.4 erupted from Active Region 3615 (beta-gamma-delta) at 21:16 UTC on March 30, 2024. The event started at 21:01 and ended at 22:15 UTC.
