Investigating the Role of 'Stealth' Coronal Mass Ejections in Intense Geomagnetic Storms
A study by astronomers highlights the significant effects of 'Stealth' Coronal Mass Ejections (CMEs), subtle solar events, on triggering intense geomagnetic storms on Earth. These CMEs, often undetectable with current technology, travel through coronal holes and can impact satellites and power grids. Through NASA's multi-spacecraft data, researchers found that these weak CMEs have major effects despite lacking typical solar eruption signals, highlighting challenges in space weather forecasting.
