Exceptional detection of an X9.0 flare by PROBA2/LYRA

On October 3, the Sun unleashed its most powerful eruption since 2017: a solar flare classified as X9.0 on the GOES scale, accompanied by a significant coronal mass ejection. We also observed a signal related to this flare in the Herzberg channel which is extremely rare.

X1.8 flare and earth-directed CME

NOAA 3848 produced a long duration X1 flare early on 9 October. The associated coronal mass ejection (CME) has arrived around 14:45UTC. The severe geomagnetic storm is nearing its end. ***UPDATED (5)***
