Since 1995, the ESA/NASA mission has watched the Sun 24/7, spotted thousands of comets, revealed the true shape of CMEs, and paved the way for today’s space-weather fleet.
Three decades. Three solar cycles. Endless discoveries. 🚀✨

☄️ See the jumps! The CME from the X5.1 flare has arrived — but it’s just getting started! Bz is northward for now, so things are calm… for the moment. Hang tight — the best may be yet to come! 🌌
Keep watch with @Vincent_Ledvina @SpaceWeather @TamithaSkov. Good luck & clear skies! ✨

🚀 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! 🌌

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! ☀️⚡️

🔥 Boom! Sunspot AR4274 just unleashed an X1.8 solar flare around 17:30 UTC — one of the most enormous bursts of energy the Sun can throw! 💥 Its magnetic field has become complex, and material has blasted into space. Could more be on the way? 🌞⚡️ Stay tuned bit.ly/sunactivity

🍁 Happy Fall / 🌸 Happy Spring!
We’re just a day past the exact #equinox but wait, there’s more! 🌍✨
You may have heard it’s when day & night are equal or when the Sun rises due east & sets due west… but that’s not the whole story.
It’s way more interesting (and a little weird 😏).
