The sun unleashed one of the biggest flares ever seen during its current activity cycle late Tuesday — an X5.4-class outburst strong enough to trigger a radio blackout. The resulting geomagnetic storm could affect electrical grids, communication links, satellite navigation systems and airline schedules over the next couple of days.

Such a storm is mainly a nuisance to satellites, causing occasional reboots of onboard computers and adding noise to imaging systems. Additionally, the Solar Radiation Storm levels remain above the S3 (Strong) threshold at this time, with values rising at the moment with the shock arrival.
