Scientists at the National Oceanic and Atmospheric Administration observed a cluster of sunspots on the surface of the sun this week. With them came solar flares that kicked off a severe geomagnetic storm. That storm is expected to last throughout the weekend as at least five coronal mass ejections — chunks of the sun — are flung out into space, towards Earth! NOAA uses a five point scale to rate these storms, and this weekend's storm is a G4. It's expected to produce auroras as far south as Alabama. To contextualize this storm, we are looking back at the largest solar storm on record: the Carrington Event. Want us to cover more about the sun? Email us at shortwave@npr.org.
