Northern Lights Dazzle Belgium After Strong Solar Storm
Belgians who looked up on the evening of Saturday, 10 October 2026 were treated to a rare sight: the aurora borealis, or northern lights, shimmering over a country far south of the usual polar viewing grounds. The display was triggered by a strong geomagnetic storm, rated G3, that followed a coronal mass ejection (CME) from the Sun two days earlier.
The aurora was reported in various locations across Belgium, a phenomenon rarely visible at the country’s relatively low latitude. According to VRT NWS, the conditions came together in what space weather expert Christine Verbeke called a textbook scenario for aurora visibility this far south.
How the Storm Reached Earth
The chain of events began on 8 October, when a coronal mass ejection left the Sun and sent a cloud of electrically charged particles hurtling toward Earth. The NOAA Space Weather Prediction Center reported that the solar wind environment became strongly enhanced when the CME arrived, and that the geomagnetic field reached G3 levels later that evening. The agency issued a G3 (Strong) or greater geomagnetic storm warning.
When charged solar particles collide with particles in Earth’s atmosphere, they release colorful light. Because Earth’s magnetic field funnels these particles toward the poles, auroras are normally best seen at high latitudes. A geomagnetic storm powerful enough can push that visibility boundary far to the south - in this case, all the way to Belgium.
A Favorable Combination of Factors
Verbeke explained that several conditions aligned to make the display possible. The solar wind reached speeds of up to about 900 kilometers per second, which she described as quite strong. The storm’s own magnetic field was also powerful, and its direction was favorable, allowing more particles to penetrate the atmosphere. Clear skies over Belgium completed the picture.
“The conditions were not exceptional, but this is a textbook example of a situation in which the northern lights can be seen as far as Belgium,” Verbeke said. “Several factors came together well.”
Still, Verbeke cautioned that the aurora was chiefly a photographic phenomenon rather than a naked-eye spectacle. “With a camera you could capture the phenomenon well, but with the naked eye it was harder to see clearly,” she said.
A Regional Event
Belgium was not alone. In the neighboring Netherlands, the aurora was also visible on Saturday evening, with observations reported from the center and south of the country, including Groesbeek. Weeronline noted that the phenomenon was barely perceptible to the unaided eye there as well, but far clearer through a good camera.
A geomagnetic K-index of 6 was recorded on 10 October, classified as a moderate space weather incident, according to the Global Incident Tracker. While the K-index of 6 corresponds to a G2 level, the broader storm reached G3 thresholds during the evening.
Not the First Time, and Perhaps Not the Last
Aurora sightings have become more frequent over Belgium in recent years, driven by a peak in solar activity. VRT NWS reported a notable display in January 2026 tied to a radiation storm rated S4 - the strongest since 2003. In November 2025, the northern lights were again seen over the north of the country.
For those who missed Saturday’s show, a follow-up opportunity was noted: the night of Sunday, 11 October offered another chance to see the northern lights above Belgium. Observers hoping to catch a glimpse are generally advised to head to the north of the country, away from light pollution, and to allow their eyes to adjust to complete darkness.
The event underscores how solar activity can ripple down to everyday life at lower latitudes, turning an ordinary night sky into a rare natural light show - one that, this time, was easiest to appreciate through a camera lens.
