Overview

• AuroraWatch UK issued a red alert at 07:06 BST on June 1, indicating a high probability of aurora visibility across Britain.
• NOAA projects a strong to severe G3–G4 geomagnetic storm from June 1 into June 2 with a chance of extreme G5 conditions lighting up northern skies in 27 states.
• The storm originates from a coronal mass ejection launched May 31 that will interact with Earth’s magnetic field to expand the auroral oval toward lower latitudes.
• Stargazers are advised to look between 9 pm and midnight under dark, cloud-free skies far from urban light pollution for the clearest views.
• This event coincides with the peak of the sun’s 11-year cycle and carries potential impacts on power grids, GPS accuracy and satellite communications.
