An approximately 25 degrees in length filament eruption centered near S35W09, began erupting after 09:00 UTC on January 22, 2024, producing an Earth-directed CME. The estimated time of arrival is January 25.
A coronal mass ejection produced by a filament eruption on January 20, 2024, is expected to reach Earth late January 22, producing G2 – Moderate geomagnetic storming.
A major X5.0 solar flare erupted from Active Region 3536 at 21:55 UTC on December 31, 2023. The event started at 21:36 and ended at 22:08 UTC. This is now the strongest solar flare of the current solar cycle — Solar Cycle 25 — and the strongest flare since X9.3 on September 6, 2017.
Multiple M-class solar flares and CMEs were recorded on December 24, 2023. Forecasts indicate potential geomagnetic disturbances with a grazing blow expected late on December 27, 2023.
A moderately strong solar flare measuring M4.2 erupted from Active Region 3519 at 05:38 UTC on December 21, 2023. The event started at 05:19 and ended at 05:49 UTC.
A major solar event occurred on December 14, 2023, when a powerful solar flare measuring X2.8 erupted from Active Region 3514. This event, which started at 16:47 and ended at 17:12 UTC, is the strongest solar flare since September 10, 2017, and the strongest solar flare of the current Solar Cycle.
A powerful solar flare measuring X2.8 erupted from Active Region 3514 at 17:02 UTC on December 14, 2023. The event started at 16:47 and ended at 17:12 UTC. This is the strongest solar flare of the current Solar Cycle.
Solar activity increased to high levels in 24 hours to 12:30 UTC on December 14, 2023, with M5.8 solar flare at 07:44 UTC from Region 3514 and multiple coronal mass ejections (CMEs).
An impulsive solar flare measuring M5.4 erupted from Active Region 3511 at 23:07 UTC on December 8, 2023. The event started at 22:57 UTC and ended at 23:14.
Multiple coronal mass ejections (CMEs) produced on November 27 and 28, 2023 are heading toward Earth, with impacts expected from late November 30 to mid-day UTC on December 1, 2023. As a result, a G3 – Strong Geomagnetic Storm Watch is in effect for December 1.
