Aurora alert: Strong geomagnetic storm could spark northern lights at mid-latitudes across US and Europe
Geomagnetic storm conditions are predicted for July 30 through Aug.1, with G3-class storms possible.
The National Oceanic and Atmospheric (NOAA) Space Weather Prediction Center has issued a geomagnetic storm warning due to strong solar activity. If the predicted G3 conditions are reached, auroras could be visible across mid-latitudes around 50°.
Previous geomagnetic storms at this magnitude have triggered auroras as low as Illinois and Oregon. The first of several incoming coronal mass ejections (CMEs) has already arrived, bringing with it a compression of multiple back-to-back solar storms that could lead to G3 or even G4-level potential.
For now, keep your eyes fixed on current space weather forecasts and make sure those camera batteries are charged! Reports of northern lights across North America have already appeared.
