Moderately strong M8.6 solar flare erupts from Region 3234
A moderately strong solar flare measuring M8.6 erupted from Active Region 3234 at 17:50 UTC on February 18, 2023. The event started at 17:35 and ended at 17:56 UTC.
Long-duration M6.3 solar flare erupts from AR 3229, CME produced, S1 solar radiation storm
A long-duration solar flare measuring M6.3 erupted from Active Region 3229 at 19:44 UTC on February 25, 2023. The event started at 18:40 and ended at 20:27 UTC.
Long-duration M3.7 solar flare erupts from AR 3229, producing large coronal mass ejection
A long-duration M3.7 solar flare erupted from Active Region 3234 at 20:30 UTC on February 24, 2023, producing a large coronal mass ejection (CME). The event was associated with a filament eruption.
Multiple M-class flares and CMEs observed
Our sun displayed high levels of activity in 24 hours to 12:30 UTC on February 9, including multiple low-level M-class solar flares and coronal mass ejections (CMEs) observed on the southeast and southwest limbs.
Double-peaked M6.3 solar flare erupts from AR 3213
Active Region 3213 rapidly emerged on the visible disk on February 6 as just a few sunspots but has since grown into a mature, magnetically-complex sunspot group, producing several M-class flares, including a double-peaked flare that began at 22:46 and peaked at 23:07 as M6.3. The first peak was registered as M3.8 at 22:58 UTC.
Long-duration M4.6 solar flare erupts from AR 3190
Solar activity has reached moderate levels in 24 hours to 12:30 UTC on January 25, with a long-duration M4.6 flare peaking at 10:11 UTC today.
Increased solar activity – glancing blow possible on January 19
Solar activity reached high levels in the past 24 hours, with the strongest event being an M6.0 flare from Region 3191. This event was accompanied by a Type II radio sweep and a Coronal Mass Ejection (CME) signature, however, analysis and modeling indicate that no Earth-directed component was produced. A CME was also observed off the southwest limb at 22:00 UTC on January 14, with analysis and modeling suggesting the possibility of a glancing blow on January 19.
Geomagnetic storms likely on January 4 and 5 due to the combined effects of a CME and CH HSS
Geomagnetic storms reaching G1 – Minor levels are likely on January 4 and 5, 2023 due to combined effects of a coronal mass ejection (CME) that left the Sun on December 30 and coronal hole high speed stream (CH HSS) effects. Solar activity is expected to be at low levels, with a chance for M-class flares through January 28.
Multiple M-class solar flares erupt from AR 3165
Multiple M- and C-class solar flares were detected on December 14, 2022, with the strongest being M6.2 at 14:42 UTC. While several coronal mass ejections (CMEs) were produced, none of them appears to be Earth-directed.
Two M1.2 solar flares erupt from Region 3141
Two M1.2 solar flares erupted from Active Region 3141 (Beta-Gamma-Delta) on November 11, 2022 – the first at 07:14 and the second at 11:40 UTC. The region is located at the center of the solar disk — coronal mass ejections (CMEs) produced by it are likely to be Earth-directed.
