X1.4 solar flare erupts on the Sun’s west limb — second X-class flare of the day
An impulsive solar flare measuring X1.4 erupted beyond the Sun’s west limb at 15:47 UTC on October 9, 2024. The event started at 15:44 and ended at 15:53 UTC.
Major X1.8 solar flare produces Earth-directed CME, impact expected late October 10
A major solar flare measuring X1.8 erupted from Earth-facing Active Region 3848 at 01:56 UTC on October 9, 2024. The event started at 01:25 and ended at 02:43 UTC. A fast-moving full halo coronal mass ejection (CME) was produced during the event, with the impact expected from late October 10 to early on October 11.
Major X2.1 and long-duration X1.0 solar flares erupt from AR 3842
A major solar flare measuring X2.1 erupted from Active Region 3842 at 19:13 UTC on October 7, 2024. The event started at 19:02 and ended at 19:31 UTC.
Major X9.0 solar flare erupts from Region 3842 — the strongest of Solar Cycle 25, Earth-directed CME produced
A major solar flare measuring X9.0 erupted from Active Region 3842 at 12:18 UTC on October 3, 2024. The event started at 12:08 and ended at 12:27 UTC. This is thus far the strongest solar flare of Solar Cycle 25.
Major X7.1 solar flare erupts from Region 3842, producing likely Earth-directed CME
A major solar flare measuring X7.1 erupted from Active Region 3842 at 22:20 UTC on October 1, 2024, producing a CME that most likely has an Earth-directed component. This is the second-strongest solar flare of Solar Cycle 25.
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.
Major X4.5 solar flare erupts from AR 3825, producing Earth-directed CME
A major solar flare measuring X4.5 erupted from Active Region 3825 at 15:29 UTC on September 14, 2024. The event started at 15:13 and ended at 15:47 UTC. This is the fifth strongest solar flare of Solar Cycle 25.
Impulsive X1.3 solar flare erupts from unnumbered region on the Sun’s SE limb
A major solar flare measuring X1.3 erupted from an unnumbered active region on the Sun’s SE limb at 09:43 UTC on Thursday, September 12, 2024. The event started at 09:31 and ended at 09:51 UTC.
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.
G3 – Strong geomagnetic storm following CME impact produced by X1.3 solar flare
The coronal mass ejection (CME) produced by the X1.3 solar flare on August 14, 2024, impacted Earth around 14:30 UTC on August 18, producing G3 – Strong geomagnetic storming.
