Longest-Ever Look at Stormy Region on the Sun Offers New Clues to Space Weather

SMRTR summary

Scientists achieved a milestone by observing a single active region on the sun for a record 94 days using the European Space Agency's Solar Orbiter mission. The observed region, NOAA 13664, was responsible for the severe geomagnetic storms in May 2024 that disrupted satellites, power grids, and GPS while producing northern lights as far south as Florida. This extended observation period provides unprecedented data that researchers hope will improve predictions of solar eruptions and help better understand how space weather affects Earth's technology and infrastructure.
