A Massive Launch Blows a Coronal Hole Wide Open | Solar Storm Forecast 5 December 2025

·18 min·1 clip

A filament eruption widened a coronal hole, potentially improving aurora conditions during its next solar rotation.

1. Space Weather Woman Forecasts and News examines December 5, 2025 solar activity through Region 4299's near-X2 flare, Region 4300's M6 flare, and an expanded coronal hole. 2. Dr. Tamitha Scove, the Space Weather Woman and forecast host, interprets solar imagery, Stereo observations, NASA's Enlil model, and NOAA outlooks. 3. The episode's central hook is that a filament eruption connected to Region 4288 widened a coronal hole, potentially changing its future fast-solar-wind impact. 4. Region 4299 produced a near-X2 flare on December 1, with a gigahertz radio burst that may have caused glitches for GPS, GNSS, and satellite phones. 5. Scove says Region 4299's filaments remain magnetically connected and could produce additional partial eruptions despite the region becoming quieter. 6. Region 4300 became the leading active region after producing an M6 flare, while a related eastward eruption could deliver a glancing blow around December 7–8. 7. The coronal-hole boundary visibly disappeared outward after the Region 4288 filament eruption, expanding the hole toward its prior-rotation size. 8. NOAA's forecast gives high latitudes up to a 55% chance of a major storm initially and approximately a 65% chance around December 7–8, while mid-latitudes receive a 35% active-condition chance. 9. Solar flux remains above 200, with NOAA estimating 75% odds of M-class flares, 25% odds of X-class flares, and a 15% chance of S1–S2 radiation storms over three days. 10. Best suited to aurora photographers, ham-radio operators, aviators, and solar-weather observers.

As heard by us

A widening coronal hole anchors a clear solar forecast about eruptions, aurora chances, and signal disruptions.

A near-X2 flare, a gigahertz-range radio burst, and an eruption that appeared to widen a coronal hole give this single-episode review its momentum. Dr.
