Game On Again! After a long stint of northward field, this last solar storm is showing some teeth! Because this one is so fast, even small dips into southward field will drive strong #aurora! Likely not as strong as yesterday, but views deep into mid-latitudes are likely tonight!

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

πŸš€ As we wait for the next CME β€” and maybe more aurora action β€” 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! 🌌

🌌 Aurora lovers, what a night! The lights danced everywhere β€” and the show’s not over yet! ✨ One more of the three CMEs from powerhouse region AR4274 is expected to hit around midday ET, which means… the aurora could light up the skies again tonight! πŸ”₯ πŸŽ₯ Join me and

πŸ”₯ Boom! Sunspot AR4274 just unleashed an X1.8 solar flare around 17:30 UTC β€” one of the most enormous bursts of energy the Sun can throw! πŸ’₯ Its magnetic field has become complex, and material has blasted into space. Could more be on the way? 🌞⚑️ Stay tuned

On the way to Iceland over the Labrador Sea aurora from the plane 10/14 at 3:45 UT then on 10/18 at 4:22 UT near Lake MΓ½vatn. Then the next night near midnight, BAM! An amazing show! 🀯Fingers crossed for more over the week. πŸ”₯@vincent_ledvina @tamithaskov #spaceweather #aurora

🌍✨ The Carruthers Geocorona Observatory is now deployed! It will study the very edge of Earth’s atmosphere β€” the geocorona β€” to see how it leaks into space & changes with solar activity. Named for space imaging pioneer George Carruthers. Watch LIVE πŸš€: https://t.co/7bl17eEIGt

IMAP is a solar wind scout. Sits at L1, million miles closer to the Sun, watching streams of particles rush toward Earth. By measuring their speed, density, and direction, IMAP helps scientists predict space weather that could disrupt satellites, power grids, & astronauts’ safety
