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.
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.
Filament eruption produces large CME, slight graze possible
A solar filament eruption centered near S35E50 took place around 20:00 UTC on March 5, 2024, producing a large coronal mass ejection (CME) which is expected to slightly graze Earth late March 8. G1 – Minor geomagnetic storms are possible on March 9 due to the combined effects of a negative polarity CH HSS and this CME.
CME impact sparks G2 – Moderate geomagnetic storm
A coronal mass ejection (CME) produced by C5.1 solar flare on February 28, 2024, impacted Earth at approximately 08:45 UTC on March 3, producing G2 – Moderate geomagnetic storming.
Major X6.3 solar flare erupts from Region 3590
A major X6.3 solar flare erupted from Active Region 3590 at 22:34 UTC on February 22, 2024. The event started at 22:08 UTC and ended at 22:43.
Major network outages in U.S. following two X-class solar flares
A widespread network outage was reported in the United States on Thursday morning, February 22, 2024, following two major eruptions on the Sun, an X1.8 flare at 23:07 UTC on February 21 and X1.7 at 06:32 UTC on February 22. Both erupted from Active Region 3590.
Two X-class solar flares – X1.8 and X1.7 erupt from Region 3590
Two X-class solar flares erupted over the past 9 hours — the first was X1.8 at 23:07 UTC on February 21 and the second X1.7 at 06:32 UTC on February 22, 2024. Both erupted from Active Region 3590.
Major X2.5 solar flare erupts from AR 3576, producing large CME
An impulsive solar flare measuring X2.5 erupted from Active Region 3576 (beta-gamma) at 06:53 UTC on February 16, 2024. The event started at 06:42 and ended at 06:58 UTC. This is the fourth strongest solar flare of Solar Cycle 25 — after X5.0 on December 31, 2023, X3.3 on February 9, 2024, and X2.8 on December 14, 2023.
Three CMEs heading toward Earth, impact expected on February 13
At least three coronal mass ejections (CMEs) are heading toward Earth. The impact is expected early on February 13 (UTC), producing G2 – Moderate or stronger geomagnetic storming.
