The largest of them was an M4.9 flare at 17:08 on April 23 from Region 4419 (beta-gamma-delta).<\/p>\n<p>The region underwent significant evolution, including flux emergence in the leading spots, flux consolidation in the intermediary regions, and the development of a delta configuration in the leader alongside a mixed-polarity gamma configuration.<\/p>\n<p>Region 4420 (beta-gamma-delta) also exhibited growth and consolidation, particularly within the trailing and intermediate spots, with increased shearing noted in intermediate areas. The remaining regions on the disk were in decay.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><figcaption class=\"wp-element-caption\">Sunspots on April 24, 2026. Credit: NASA SDO\/HMI<\/figcaption><\/figure>\n<\/div>\n<p>Notable eruptive activity was observed throughout the 24-hour period, with CMEs associated with each of the M-class flares.<\/p>\n<p>A CME was observed to the NW following an M1.6 flare from Region 4419 at 04:35 UTC on April 23 and was first visible in LASCO C2 imagery at 05:00 UTC, while a CME to the NE was associated with an M1.2 flare from Region 4420 at 05:08 UTC on April 23 and first visible at 05:12 UTC.<\/p>\n<p>These events were accompanied by Type II (1 033 km\/s) and Type IV radio emissions. Modeling indicates the NW CME will pass ahead of Earth, while the NE CME is expected to result in a glancing impact on April 26.<\/p>\n<p>Subsequent flaring from Region 4419 that are associated with observed eruptions include an M4.3 flare from Region 4419 at 08:53 UTC on April 23 which produced a NW CME (first seen at 09:12 UTC) associated with Type II emissions (722 km\/s) and 10cm radio bursts, an M1.7 flare from Region 4419 at 14:00 UTC on April 23 which launched a NE CME (first seen at 14:24 UTC), and an M4.9 event at 17:08 UTC which produced an additional NE CME (first seen in GOES-19 CCOR1 at 18:15 UTC).<\/p>\n<p>While analysis of the eruption associated with the M4.9 flare is ongoing, none of these are anticipated to impact Earth.<\/p>\n<p>Finally, a diffuse eruption was observed in STEREO COR2 imagery at 12:23 UTC and LASCO C2 at 12:24 UTC. The source remains uncertain, with possibilities including a SE filament eruption or NE coronal dimming. Analysis of this event, as well as the potential for interaction between the multiple preceding CMEs, is ongoing.<\/p>\n<p>Solar activity is expected to be at moderate levels through April 26, with a chance for X-class flares primarily driven by the ongoing complexity of Regions 4419 and 4420.<\/p>\n<p>The likelihood for M-class flares is anticipated to increase today as a large sunspot region, currently identified in Solar Orbiter imagery beyond the east limb, rotates onto the visible disk.<\/p>\n<p>The greater than 2 MeV electron flux is expected to be at moderate to high levels through April 26, primarily influenced by a weak positive polarity coronal hole high-speed stream (+CH HSS).<\/p>\n<p>Transient flux suppressions are possible on April 26 from the anticipated glancing influence of the CME associated with the M1.2 flare from Region 4420.<\/p>\n<p>The greater than 10 MeV proton flux is expected to remain at background levels, though there is a slight chance (10%) for levels to exceed S1 \u2013 Minor solar radiation storm thresholds due to the flare potential of Region 4419 as it rotates toward the western limb.<\/p>\n<p>Solar wind parameters are expected to experience mild enhancements beginning April 24 due to the onset of a +CH HSS. Further enhancements are anticipated on April 26 associated with the arrival of the glancing influence from the CME originating from the M1.2 flare from Region 4420.<\/p>\n<p>The geomagnetic field is expected to be mostly quiet to unsettled on April 24 and 25, with isolated active periods possible as the +CH HSS influences persist. Isolated G1 \u2013 Minor geomagnetic storming conditions are possible on April 26 in response to the arrival of the glancing CME impact.<\/p>\n<p>References:<\/p>\n<p><sup>1<\/sup> Forecast Discussion \u2013 NOAA\/SWPC \u2013 Issued at 00:30 UTC on April 24, 2026<\/p>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/watchers.news\/2026\/04\/24\/major-x2-4-solar-flare-april-24-2026\/?rand=772108\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A 10 cm Radio Burst (TenFlare) lasting 6 minutes and with peak flux of 570 sfu was registered from 01:03 to 01:09 UTC.
