NOAA’s Space Weather Prediction Center – the nation’s official source of warnings and alerts about space weather and its impacts on Earth – is evaluating the potential for a moderate to strong geomagnetic storm resulting from a significant explosion from the sun’s corona Tuesday evening. G-scale solar storms range from G1 (minor) to G5 (extreme). The so-called coronal mass ejection may reach Earth by early Thursday morning. Geomagnetic storms on Earth can impact the operation of electrical grids and temporarily disrupt radio and satellite telecommunications.
The radiation storm associated with this event is already triggering high-frequency radio blackouts at Earth’s poles and in several other regions of the planet. High-frequency radio is used by airlines flying over the poles, emergency managers and others.
NOAA’s space weather experts are available to discuss the evolving forecast and understanding of this event.
