Another view of this impressive event which is not yet over - we are still above the M5 threshold over one hour in with multiple peaks over X-class. The largest flare was an X8.1 - one of the strongest flare intensities in 20 years and the strongest of this solar cycle.

BAM! Another X flare! 💥 Looks like an old visitor is rotating back into view — and it made its presence known with an X1.2 flare around 22:30 UTC. Keep ’em coming, Sun! ☀️⚡️

🚀 As we wait for the next CME — and maybe more aurora action — here’s a look at what’s racing toward Earth! ⚡️ This eruption and CME blasted out with yesterday’s X5.2 flare, complete with a powerful shock and particles hitting the cameras. Fingers crossed 🤞 and skies clear! 🌌
