G4 – Severe geomagnetic storm in progress
A coronal mass ejection (CME) produced on June 25, 2024, impacted Earth shortly after 09:30 UTC on June 28, producing G4 – Severe geomagnetic storm.
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.
Epic solar storm impacts Mars
May 2024 saw increased solar activity, leading to numerous significant events including a rare G5 – Severe geomagnetic storm and a powerful solar flare directed at Mars on May 20. This event, estimated at X12, sent X-rays, gamma rays, and charged particles toward the red planet, providing valuable data for future Mars missions.
G2 – Moderate geomagnetic storm watch, X1.5 flare erupts from departing Region 3697
A G2 – Moderate geomagnetic storm watch is in effect for June 10, 2024, due to the anticipated arrival of coronal mass ejection (CME) produced by a long-duration M9.7 solar flare on June 8.
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.
Impulsive X1.1 solar flare erupts from Region 3697
An impulsive solar flare measuring X1.1 erupted from Active Region 3697 at 22:03 UTC on May 31, 2024. The event started at 21:52 and ended at 22:03 UTC.
Long-duration X1.4 solar flare erupts from old region 3664, partial halo CME produced
A major, long-duration solar flare measuring X1.4 erupted from Active Region 3697 (previously numbered 3664) at 14:37 UTC on May 29, 2024. This is the second X-class solar flare since May 27.
Major X2.8 solar flare erupts from old Region 3664 — now returning into Earth view
A major solar flare measuring X2.8 erupted from the Sun’s southeast limb at 07:08 UTC on May 27, 2024, producing a strong coronal mass ejection (CME). The event started at 06:49 and ended at 07:25 UTC.
Major X2.9 flare erupts on SE limb of the Sun, signals new wave of heightened solar activity
A powerful solar flare measuring X2.9 erupted on the Sun’s southeastern limb at 14:38 UTC on May 15, 2024. The event started at 14:20 and ended at 14:51 UTC. This is the second X-class solar flare after X3.4 at 08:37 UTC from Region 3664 — off the west limb.
