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.
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.
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.
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.
Proton flux rising after powerful farside eruption, S1 – Minor solar radiation storm
Proton flux started rapidly rising at 07:30 UTC on February 12, 2024, following what appears to be an eruption from the old Region 3575 – now traversing the farside of the Sun.
M6.5 solar flare erupts from AR 3576, G2 – Moderate geomagnetic storm watch
A moderately strong M6.5 solar flare erupted from Active Region 3576 at 03:48 UTC on February 12, 2024. The event started at 03:23 and ended at 03:53 UTC.
Strong M9.0 solar flare erupts from geoeffective Region 3576
A strong solar flare measuring M9.0 erupted at 23:07 UTC on February 10, 2024 from geoeffective Active Region 3576. The event started at 22:56 and ended at 23:14 UTC.
Major X3.3 solar flare erupts behind the SW limb, S2 – Moderate solar radiation storm
A powerful solar flare measuring X3.3 erupted behind the SW limb of the Sun (AR 3575) at 13:14 UTC on February 9, 2024. This solar flare is the second most intense in Solar Cycle 25, following an X5.0 flare that occurred on January 31, 2023.
