Four X-class solar flares (X1.0, X8.1, X2.8, X1.6) erupted from sunspot group RGN 4366 on Feb 1–2, 2026, signaling lively space weather with potential energetic particle events and possible coronal mass ejections. Forecasters say more activity could follow as the active region evolves, with potential impacts on satellites, communications, and power grids if Earth-directed CMEs occur.
NOAA reports an X8.1 flare from active region 4366, with CME modeling indicating much of the ejected material will pass by Earth to the north and east late Feb 5 UTC, potentially delivering glancing effects. The region remains highly active with ongoing M and X-class flares, and forecasters expect more activity in the coming days.
Over a 24-hour period the Sun released a barrage of flares from sunspot AR4366, including at least 18 M-class and three X-class events (peaking at X8.3), triggering radio blackouts in parts of the South Pacific and eastern Australia/New Zealand. AR4366 is rapidly growing and could produce more eruptions; a CME is expected but likely to miss Earth or only glance Earth around Feb. 5, potentially elevating high-latitude aurora activity. Forecasters warn conditions remain uncertain as activity continues.
NOAA reports an X8.1 solar flare from Region 4366; the associated CME is expected to pass by Earth to the north and east with possible glancing impacts around Feb 5 UTC; forecasters anticipate continued activity from this region in the coming days.
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 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.
A massive coronal mass ejection from the Sun is expected to slam into Earth, potentially lighting up the night sky with auroras across as many as 24 U.S. states tonight (Jan. 19) as geomagnetic activity increases.
A powerful X-class solar flare and a fast coronal mass ejection could spark auroral displays much farther south than usual tonight—potentially visible from parts of California, the central Plains, and the Mid-Atlantic, with even deeper-south areas possible. NOAA has issued a rare G4 geomagnetic storm potential, though whether the CME hits Earth head-on remains uncertain. For best viewing, find a dark, clear sky along the northern horizon after sunset.
The northern lights may be visible in several northern U.S. states on Wednesday due to geomagnetic storms caused by solar winds and a coronal mass ejection, with brighter and more widespread displays possible as a result.
Astronomers have detected a massive stellar eruption from a star 130 light-years away, providing the first strong evidence of coronal mass ejections beyond our solar system, which could impact the habitability of nearby planets and inform our understanding of space weather risks.
Astronomers have observed the first confirmed coronal mass ejection (CME) from an alien star, a red dwarf 130 light-years away, which was powerful enough to strip a planet's atmosphere, raising concerns about the habitability of planets around such active stars and advancing our understanding of stellar space weather.
The interstellar object 3I/ATLAS, a potentially massive comet-like body, is passing through the solar system at high speed, recently encountering a solar plasma blast from the Sun. Its trajectory and composition are unusual, prompting speculation about its nature, with some scientists considering extraterrestrial origins. It will closely pass Mars next week, providing an opportunity for further observation.
The interstellar object 3I/ATLAS, believed to be a comet, is rapidly traveling through the solar system and recently encountered a solar plasma blast from the Sun. Its trajectory, size, and composition are unusual, prompting speculation about its nature, with some scientists suggesting it could be extraterrestrial technology or a much larger object than previous interstellar visitors. It will pass close to Mars next week, providing an opportunity for further observation.
A massive inverted 'S' shaped solar structure, ten times the size of Earth, was observed on the Sun, followed by a coronal mass ejection that caused a mild geomagnetic storm on Earth, highlighting the importance of monitoring solar activity and its potential impacts on our planet.
A hole in the sun's atmosphere and a coronal mass ejection may trigger visible Northern Lights in the U.S. this weekend, especially around the equinox, with potential for impressive auroras due to increased geomagnetic activity.
