AR 4274 is rotating back into Earth's firing line for the 3rd time! 🌍☀️ It's been busy throwing out eruptions while on the farside, along with other ARs keeping things lively. The recent M-class flare and latest data suggests it may still be quite complex 👀

📊 Latest HUXt forecast shows 2 CMEs from AR4274 arriving on 12 Nov at ~4 & 15UT respectively. AR4274 is delivering a one-two punch!⚡️🥊 G2+ storm conditions increasingly likely. Aurora prospects strong for northern UK despite poor weather forecast.

🚨 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 👀

🚨 What we have been waiting for. AR 4274 just unleashed an X1.8 solar flare! 💥 We will have to wait and check the data to see if this beast erupted and if there's an Earth-directed CME heading our way 🌞💨🌍
Updates to follow!
