On Nov. 11, 2025, Earth experienced a severe geomagnetic storm triggered by solar flares and coronal mass ejections from an active sunspot region. While this kind of storm brings beautiful auroras admired in many areas around the world, it can also cause ionospheric disturbances that disrupt radio waves and affect crucial technologies. A new study, published in Geophysical Research Letters, found that disruptions caused by this storm scrambled GPS signals in areas where such disruptions have never been reported.
