A major, long-duration solar flare measuring X1.8 erupted from Active Region 3872 at 07:19 UTC on October 26, 2024. The event started at 05:57 and ended at 07:56 UTC. A large coronal mass ejection (CME) was produced during the event.
Coronal mass ejection (CME) produced by X1.8 solar flare on October 9, 2024, impacted Earth at 15:15 UTC on October 10, at nearly 2.4 million km/h (1.5 million miles per hour), triggering G4 – Severe geomagnetic storm.
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.
A strong solar radiation storm is currently in progress as a result of a major X1.8 solar flare at 01:56 UTC on October 9, 2024.
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.
The coronal mass ejection (CME) produced by the X9.0 solar flare on October 3, 2024, impacted Earth around 07:30 UTC on October 6, elevating solar wind parameters.
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.
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.
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.
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.
