A significant M7.1 solar flare occurred on December 31, 2025, originating from sunspot region 4324, accompanied by a coronal mass ejection (CME) that is expected to cause minor G1 geomagnetic storm conditions on Earth by January 2, 2026, with the majority of the CME heading away from Earth.
A powerful X1.9 solar flare from sunspot AR4299 caused radio blackouts in Australia and Southeast Asia, with further solar activity expected from the larger, more complex sunspot AR4294, potentially leading to additional flares and minor geomagnetic storms in the coming days.
A potential G2 to G3 geomagnetic storm caused by a recent solar flare and coronal mass ejection may make the Northern Lights visible across 22 U.S. states and parts of Canada from December 3-4, with the best viewing conditions in dark skies, amid increased solar activity and sunspots.
A G4 geomagnetic storm caused by a solar flare may bring the northern lights to New York City tonight, with the best viewing areas in central and northern parts of the state, despite light pollution and cloud cover, offering a rare celestial display.
A coronal mass ejection from a recent solar flare may cause strong aurora displays across at least 17 U.S. states, including Alaska and Illinois, tonight, with the best viewing times between 7 p.m. and 4 a.m. EST, depending on geomagnetic activity.
A powerful X1.2 solar flare from sunspot region 4274 has launched a likely Earth-directed coronal mass ejection (CME), which may arrive within 12 hours and potentially cause moderate to strong geomagnetic storms on November 12, 2025.
Active Region 4274 produced an X1.2 solar flare, following an earlier X1.7 flare, with ongoing potential for more flares and radio disruptions, impacting HF radio and navigation signals.
NOAA reports minor space weather disruptions from solar activity, including weak HF radio and navigation signal degradation, with a likelihood of R1-R2 solar flares during the week of November 3-7, 2025.
Region 4274 remains the primary source of solar flare activity, with increased complexity, impacting space weather conditions and causing minor disruptions to HF radio and navigation signals.
The Daniel K. Inouye Solar Telescope in Hawaii captured the clearest images ever of a solar flare, revealing unprecedented details of coronal loops that could revolutionize our understanding of the Sun's magnetic structure and improve space weather predictions.
A powerful solar storm caused by a recent solar flare is expected to produce visible northern lights across a broader area of the U.S., including parts of Iowa, Oregon, and Pennsylvania, from Monday to Tuesday, as forecasters warn of a geomagnetic storm.
Astronomers have captured the most detailed images yet of a powerful X-class solar flare, revealing the smallest coronal loops ever observed and providing new insights into the Sun's magnetic activity and flare architecture, which could improve understanding of solar storms affecting Earth.
The NSF Inouye Solar Telescope captured its first X-class solar flare in unprecedented detail, revealing structures like tiny coronal loops at scales as small as 21 kilometers, providing new insights into the Sun's most energetic eruptions and magnetic reconnection processes.
Scientists captured the most detailed images of a solar flare ever using the Inouye Solar Telescope, revealing plasma loops as small as 13 miles across, which could enhance understanding of solar flare mechanics and magnetic reconnection.
The Inouye Solar Telescope captured the highest-resolution images of a solar flare, revealing ultra-fine coronal loops as small as 21 km, potentially revolutionizing our understanding of solar magnetic structures and flare mechanisms.
