A huge, butterfly-shaped coronal hole has opened on the Sun and itβs so large that it spans nearly 35 times the width of Earth. These dark regions appear when the Sunβs magnetic field stretches outward, creating pathways for fast solar wind to stream into space.
Because this hole is enormous, it can send stronger bursts of solar wind toward Earth. That can lead to brighter auroras, mild geomagnetic shakes, and brief interruptions in satellite signals or radio communications.
