Orbiting camera spots vivid auroras over Iceland and Canada during a minor geomagnetic storm
A NASA/NOAA VIIRS satellite captured grayscale aurora displays over the Denmark Strait toward Iceland and across eastern Canada during a minor G1 geomagnetic storm on Feb. 16, 2026. The article explains auroras form when solar particles are channeled by Earth's magnetic field and collide with atmospheric gases, producing greens at mid-altitudes with possible magentas and reds at higher/lower altitudes; ground observers would have seen shimmering curtains under the right conditions.
