A strong M6.9 solar flare erupted from Active Region 4513 near the center of the visible solar disk at 10:02 UTC on August 25, 2026, causing an R2 – Moderate radio blackout. NOAA’s Space Weather Prediction Center (SWPC) said the associated CME and a second CME linked to a C4.7 flare and filament eruption later that day contained Earth-directed components, prompting a G2 – Moderate Geomagnetic Storm Watch for August 28. A G1 – Minor watch is in effect for August 27 due to an approaching coronal-hole high-speed stream.

Solar activity reached moderate levels on August 20, 2026, after Region 4513 produced an M8.1 flare at 11:42 UTC, the strongest of three M-class flares reported during the preceding 24-hour period. The flare was accompanied by Type II radio sweeps with an estimated velocity of 1 201 km/s

A long-duration M1.9 flare from Active Region 4492 coincided with a filament eruption near N20W67, producing an eruptive sequence associated with an Earth-directed partial-halo CME and an S1 - Minor solar radiation storm on July 30, 2026. WSA-Enlil model runs placed a possible CME arrival at Earth early on August 2, when NOAA’s Space Weather Prediction Center expects G1-G2 (Minor-Moderate) geomagnetic storm conditions.

A major solar flare measuring X1.3 erupted from newly numbered Active Region 4482 on the southeast limb at 20:41 UTC on July 4, 2026. A coronal mass ejection (CME) was produced, but due to the location of the source region, an Earth-directed component is unlikely.

A coronal mass ejection (CME) associated with the June 30, 2026, solar flare reached Earth on July 3, triggering a geomagnetic disturbance that intensified to G3 – Strong storm levels early July 4.

Multiple coronal mass ejections linked to repeated eruptions from Active Region 4479 are forecast to reach Earth in stages from July 3 through July 6, 2026. NOAA’s official forecast calls for G1–G2 geomagnetic storm conditions on July 3 and 4, while later CME arrivals remain under model assessment.

An X1.1 solar flare from Active Region 4479 produced a full-halo coronal mass ejection (CME) on June 30, 2026, prompting SWPC to issue a G2 - Moderate Geomagnetic Storm Watch for July 3.

A strong solar flare measuring M5.8 erupted from Active Region 4475 located at the west limb at 12:57 UTC on June 30, 2026. The event started at 12:37 and ended at 13:23 UTC.

A strong M6.8 solar flare erupted from Active Region 4473 on June 21, 2026, becoming the strongest flare produced by the region so far and the strongest since X1.0 on June 3. The event began at 19:17 UTC, reached maximum intensity at 19:29 UTC, and ended at 19:35 UTC.

A coronal mass ejection (CME) associated with an M1.8 solar flare from Region 4461 is forecast to arrive around midday UTC on June 8. Forecast calls for G1 - Minor to G2 - Moderate storming on June 8 and early June 9, and isolated G3 - Strong periods on June 8.
