Category G2 – Moderate geomagnetic storm predicted for November 29
A coronal mass ejection (CME) associated with filament eruption near Region 3901 at around 20:24 UTC on November 25, 2024, is forecast to reach Earth late November 28 (UTC).
M9.4 solar flare erupts beyond northeastern limb
A strong solar flare measuring M9.4 erupted beyond the Sun’s northeastern limb at 07:42 UTC on November 25, 2024. The event started at 07:24 and ended at 08:03 UTC.
Solar radiation storm reaches S2 – Moderate level following farside eruption
A strong solar flare erupted well beyond the west limb of the Sun at approximately 18:00 UTC on November 21, 2024. This event produced a large coronal mass ejection (CME) and sparked a solar radiation storm on Earth reaching S2 – Moderate levels on November 22.
