🚨 Here we go again! X4.05 flare detected from AR4274! 🚨 Although the active region is rotating towards the limb it continues to produce major flares. Proton flux measurements are also showing an increase. AR4274 keeps delivering!☀️

This active region on the sun, formerly AR4246, caused a lot of activity in October. Now it's traveled all the way around and reappeared on the Earth-facing side again, renumbered AR4274. And it's already release an X-flare. #Astronomy #Astrophotography

🚨 AR4274 just fired off another X-class flare! ⚡
CME confirmed, main bulk doesn't appear Earth-directed, though it's difficult to determine atm. If AR4274 keeps this up... are we heading for a situation similar to May 2024? Keep watching 👀

X1.79 flare from Earth-facing AR4274 just after 0730 UTC this morning with a possible full halo CME to accompany it - hopefully this CME is a bit more interesting than the duds earlier this week.

CME arrival!🎯 Real-time solar wind data from ACE at L1 showing the first CME from AR4274 is arriving.⚡
This is the start of a long geomagnetic storming period - aurora chasers, get ready! 👀🌌

Solar flare/CME alert:
An M1.8 flare peaked at 07h10 UT 07 Nov. Type II and type IV radio emissions were observed, indicating the release of another CME from AR4274.
As AR4274 turns more towards Earth, CMEs will start to have more geomagnetic impact.

Heads up, folks!
Two Earth-directed coronal mass ejections from the Sun are expected to arrive tonight(ish) and predicted to hit Class-G4 tomorrow evening, thanks to an X1.2 flare unleashed by the AR4274 region on Sol.
Thanks to Earth's magnetic field we'll be safe.
But there might be .. AURORAS!

L’évènement semble violent et rapide, on attend plus d’images, mais ça risque d’être bien sympa pour les aurores si c’est bien orienté !
