A major solar flare registered as X2.0 erupted from Active Region 3878 at 21:20 UTC on October 31, 2024. The event started at 21:12 and ended at 21:27 UTC. The flare was immediately followed by a long-duration M9.5 flare. Meanwhile, the solar radiation storm that started on October 26 entered the 7th day and continues at S1 – Minor levels.
A solar radiation storm reached S2 – Moderate levels on October 27, 2024, following a powerful X1.8 flare on October 26. Elevated levels of high-energy protons are expected to persist, potentially impacting high-altitude flights, satellite operations, and polar radio communications.
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.
A major, long-duration solar flare measuring X3.3 erupted from the Sun’s southeast limb at 03:57 UTC on October 24, 2024. The event started at 03:30 and ended at 04:28 UTC. The source is returning Region 3842.
NASA and NOAA announced on October 15, 2024, that the Sun has officially entered its solar maximum phase, a period marked by heightened sunspot activity, expected to continue into 2025.
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.
