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.
Models show multiple incoming CMEs, G3 – Strong or higher geomagnetic storm forecast
At least three coronal mass ejections (CMEs) are expected to strike Earth from October 5 to 7, prompting a G3 – Strong Geomagnetic Storm Watch, with the possibility of G4 – Severe geomagnetic storm conditions.
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.
G4 – Severe geomagnetic storm after CME produced by X4.5 solar flare impacts Earth
The coronal mass ejection (CME) produced by the X4.5 solar flare on September 14, 2024, hit the Earth’s magnetic field at 23:29 UTC on September 16, sparking G4 – Severe geomagnetic storm. This was the fifth strongest solar flare of Solar Cycle 25.
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.
CME impacts Earth, sparking G3 – Strong geomagnetic storm and widespread red aurora
Coronal mass ejection (CME) produced by a filament eruption early Sunday, September 8, 2024, hit Earth at around 03:50 UTC on September 12. The impact sparked G3 – Strong geomagnetic storming and widespread red aurora.
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.
Filament eruption produces Earth-directed CME; S1 – Minor solar radiation storm in progres
Early on Sunday, September 8, 2024 (UTC), a magnetic filament erupted from the Sun’s northwest quadrant (N16W22), releasing an Earth-directed coronal mass ejection (CME). The CME is expected to impact Earth on September 10, potentially triggering a G2 – Moderate geomagnetic storm. Concurrently, heightened activity near the Sun’s west limb has caused a sharp increase in proton levels, resulting in an S1 – Minor solar radiation storm at 08:50 UTC today.
