Solar Max Sparks Southern UK Auroras

Auroras lit up the South West of the UK (Devon, Cornwall and the Channel Islands) due to coronal mass ejections from the Sun at the height of solar cycle 25. Experts say 2025–2026 is the likely peak, with some forecasts suggesting the next maximum could be as late as 2037. Strong geomagnetic storms push auroras farther south, but visibility depends on dark skies and viewing conditions. To see them, monitor Met Office Space Weather alerts and head to dark-sky sites away from light pollution, using long-exposure photography; the article notes several South West dark-sky locations.

Solar storm lights up auroras from Europe to Southern California, 23-year radiation record broken

A powerful solar radiation storm triggered by an X-class solar flare and a CME struck Earth, producing widespread auroras across Europe and parts of North America, with sightings as far south as Southern California. The storm peaked at G4 (severe) on the geomagnetic scale per NOAA’s SWPC. While dramatic, it wasn’t the strongest in two decades (the 2024 Mother’s Day event held that distinction), but it did set a 23-year record for solar-radiation storms.

Earth Faces a 20-Year-High Solar Storm: What This Powerful Space Weather Means

Earth has been hit by the strongest solar radiation storm in more than two decades, driven by activity from the Sun. The resulting geomagnetic disturbance could affect radio communications, satellite operations, and power/stability of certain technologies, while also lighting up spectacular auroras at lower latitudes. Space weather agencies are monitoring the event and the potential cascading effects over the coming hours to days, offering updates and guidance for affected systems.

Severe Solar Storm Sparks Auroras at Unusual Latitudes

Earth is under a severe geomagnetic storm (G4, potentially reaching G5) triggered by a large coronal mass ejection and fast solar wind after an X1.9 flare, fueling strong auroras that could appear at unusually low latitudes; a radiation storm (S4, now subsiding to S2) also poses risks to spacecraft, aviation, and satellites, while power grids and communications may be affected as Earth's magnetic field responds to ongoing solar wind.

Rare aurora could glow over north Georgia as space storm hits

Rare aurora could glow over north Georgia as space storm hits

A strong G4 geomagnetic storm triggered by a solar flare and coronal mass ejection could produce faint northern lights visible in north Georgia tonight, depending on a KP index of 8–9. Observers should seek dark skies away from city lights, and a visible aurora may be hard to see with the naked eye. Solar storms can also affect GPS, satellites, and power grids.

Rare southern auroras possible as strong geomagnetic storm hits

A major geomagnetic disturbance could light up the sky with auroras across Canada and much of the northern US on Monday night, possibly stretching farther south; NOAA's space weather center warns the storm is among the strongest in more than two decades and could disrupt satellites and GPS, with activity expected to persist into Tuesday, following November events that brought auroras as far south as Kansas, Colorado, and Texas.

CME Arrival Triggers G4 Geomagnetic Storm Watch for Jan 20

NOAA’s Space Weather Prediction Center has issued a G4 (Severe) Geomagnetic Storm Watch for January 20 due to a coronal mass ejection released January 18 in association with an energetic solar flare; the CME is expected to reach Earth from late January 19 to early January 20, with storm levels potentially ranging from G1 to G3 upon arrival and the passage likely continuing through January 20, with residual effects possible on January 21. Forecasters have a fair degree of confidence in the timing and will provide updates as conditions evolve.
