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.

A G3 - Strong Geomagnetic Storm Watch is in effect for June 4 and 5, 2026, following three significant solar flares from Active Region 4455. NOAA’s Space Weather Prediction Center (SWPC) issued the watch at 14:52 UTC on June 3 after Earth-directed CME components were identified from two eruptions earlier in the day.

An X1.0 solar flare erupted from Active Region 4455 at 11:28 UTC on June 3, 2026, producing R3 - Strong radio blackout conditions on the sunlit side of Earth. This is the third major flare from the same region today, following M9.3 at 01:36 UTC and M7.7 at 07:00 UTC.

A strong solar flare measuring M9.3 at its peak erupted from Active Region 4455 at 01:36 UTC on June 3, 2026, producing an Earth-directed coronal mass ejection (CME). The event started at 01:22 UTC and ended at 01:43 UTC. At 07:00 UTC, another strong solar flare -- M7.7 -- erupted from the same region and produced another Earth-directed CME.

High-energy solar protons briefly reached S1 - Minor solar radiation storm levels on May 26, 2026, following a large partial halo coronal mass ejection (CME) from the far side of the Sun. The eruption was first detected by the GOES-19 CCOR-1 coronagraph at 22:00 UTC on May 25. Forecast calls for a 10% chance of another S1 or stronger solar radiation storm on May 27.

A moderately strong solar flare measuring M1.9 erupted from geoeffective Active Region 4436 at 16:12 UTC on May 16, 2026. A coronal mass ejection (CME) was produced, but analysis remains incomplete pending coronagraph imagery.

A G2 - Moderate geomagnetic storm watch is in effect for May 15, 2026, due to the anticipated impact of a corotating interaction region (CIR) associated with a negative polarity coronal hole high speed stream (CH HSS). G1 conditions are forecast for May 16 and 17.

A moderately strong solar flare measuring M5.7 at its peak erupted from Active Region 4436 at 13:39 UTC on May 10, 2026. The event started at 13:19 and ended at 14:02 UTC.

Solar activity reached high levels on April 26, 2026, after Region 4420 produced an M6.0 flare at 22:57 UTC, reaching R2 – Moderate radio blackout level. NOAA’s Space Weather Prediction Center (SWPC) forecasts a 70% chance of additional M-class flares capable of R1–R2 radio blackouts and a 25% chance of X-class flares capable of R3 or greater events through April 29.

Blue auroras could be possible over Arctic regions in late April 2026 as seasonal solar geometry allows sunlight to illuminate the upper atmosphere while ground-level skies remain sufficiently dark. The phenomenon is linked to ionized nitrogen emissions that are typically too faint to detect but can be amplified under these conditions.
