Severe Storms Could Send Northern Lights to the Deep South

January 21, 2026

A rare and powerful “double-header” of space weather is currently rattling Earth’s magnetic field. For the first time in over two decades, the sun has unleashed a combination of a G4 (Severe) geomagnetic storm and an S4 (Severe) solar radiation storm, creating a unique window for aurora hunters far beyond the typical polar regions.

While space weather sounds like something out of a sci-fi novel, the effects are very real—and potentially beautiful. This isn’t your average solar flare. The S4 radiation storm currently in progress is the strongest recorded since the famous “Halloween Storms” of 2003. According to NOAA’s Space Weather Prediction Center (SWPC), these events are triggered by a massive X-class solar flare that launched a “fast bubble” of solar material—a Coronal Mass Ejection (CME)—directly toward Earth.

What this means for us:

The Glow: The geomagnetic storm is powerful enough to push the “auroral oval” (the ring where lights appear) significantly southward.
The Tech: Experts have warned of potential disruptions to GPS, satellite operations, and high-frequency radio, particularly for trans-polar aviation.
The Safety: NOAA emphasizes that while the storm is “severe” for technology, there is no direct harm to people on the ground

The sun is currently in its Solar Maximum phase—the peak of its 11-year cycle. This means 2026 is expected to be a blockbuster year for solar activity. While the peak of this current storm was reached around January 19–21, lingering effects and secondary “shocks” from the sun’s magnetic field (specifically the $B_z$ orientation) mean the sky could still hold surprises over the coming nights.
