Long-duration M9.4 solar flare erupts from Region 3615
A long-duration solar flare measuring M9.4 erupted from Active Region 3615 (beta-gamma-delta) at 21:16 UTC on March 30, 2024. The event started at 21:01 and ended at 22:15 UTC.
Strong X1.1 solar flare erupts from AR 3615
A strong X1.1 solar flare erupted from Active Region 3615 at 20:56 UTC on March 28, 2024. The event started at 20:50 and ended at 21:01 UTC.
G3 – Strong geomagnetic storm predicted for March 25; 19 M-class flares in 25 hours
Coronal mass ejection (CME) produced by the X1.1 solar flare at 01:33 UTC on March 23, 2024, is expected to impact Earth late March 24 or early March 25, producing G2 – Moderate to G3 – Strong geomagnetic storming.
Major, long-duration X1.1 solar flare produces Earth-directed CME
A major, long-duration solar flare measuring X1.1 erupted from Active Region 3614 at 01:33 UTC on March 23, 2024. The event started at 00:58 and ended at 02:21 UTC. A halo CME was produced, with impacts to Earth likely late March 25 or early March 26.
Strong M7.4 solar flare erupts from AR 3615
A strong solar flare measuring M7.4 erupted from Active Region 3615 at 07:36 UTC on March 20, 2024. The event started at 07:23 and ended at 07:47 UTC.
Strong M6.7 solar flare erupts from emerging region on SE limb
A strong solar flare measuring M6.7 erupted from a new region emerging on the SE limb (AR 3615) at 19:19 UTC on March 18, 2024. The event started at 19:02 UTC and ended at 19:28 UTC.
Filament eruption produces Earth-directed CMEs
A filament channel eruption, approximately 35 degrees in length, began at around 01:00 UTC on March 17, 2024, producing two coronal mass ejections (CMEs).
Strong solar flare erupts from the SE limb, signaling increased solar activity in the days ahead
A moderately strong solar flare registered as M3.5 erupted from the southeast limb of the Sun at 16:35 UTC on March 16, 2024. The event started at 16:22 and ended at 16:44 UTC. This flare was partially eclipsed by the edge of the Sun, which means it was much stronger than M3.5.
Proton flux rising following multiple long-duration C-class flares, S1 – Minor solar radiation storm
Although solar activity was at low levels over the past 24 hours, multiple long-duration C-class solar flares, associated with activity from Region 3599 as it rotated beyond the west limb, produced coronal mass ejections (CMEs) that sent proton flux rising to S1 – Minor levels.
Strong M7.4 solar flare erupts from AR 3599, producing CME
A strong solar flare measuring M7.4 erupted from Active Region 3599 (beta-gamma-gamma) at 12:13 UTC on March 10, 2024. The event started at 12:00 UTC and ended at 12:20.
