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.
A strong solar flare measuring X1.4 erupted from Region 3697 (ex 3664) at 08:48 UTC on June 1, 2024. The event started at 08:26 and ended at 08:58 UTC.
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.
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.
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.
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.
A powerful solar flare registered as X3.4 erupted from Active Region 3664 — now located beyond the west limb — at 08:37 UTC on May 15, 2024. The event started at 08:18 and ended at 08:52 UTC. A solar radiation storm continues at S1 – Minor to S2 – Moderate levels since May 13.
A powerful solar flare measuring X8.7 erupted from Active Region 3664 — currently located at the west limb of the Sun — at 16:51 UTC on May 14, 2024. The event started at 16:46 and ended at 17:02 UTC.
Active Region 3664 — the source of numerous Earth-directed coronal mass ejections (CMEs) over the past 7 days — began its transit of the western limb on May 13, 2024. The region remains very active, producing a long-duration M6.6 flare on May 13, associated with a likely Earth-directed CME, and an X1.7 at 02:09 UTC on May 14. Meanwhile, a solar radiation storm is in progress due to activity associated with the same region.
Thanks to Gianluca Masi of the Virtual Telescope Project, we have an exceptional video showcasing auroral activity from May 10 and 11, 2024, during a G5 – Extreme geomagnetic storm.
