The #sunspot-littered #Sun at 14:42 UTC today, taken with a #BridgeCamera at high (slightly digital) zoom through old aluminized-mylar eclipse glasses: four of the 6 current groups - https://spaceweather.com/images2026/29jun26/hmi1898.gif - are easily seen, big 4478 and 4479 well resolved into umbra and penumbra and small 4480 and 4475.

🚨 BIG SUNSPOT ALERT 🚨 Sunspot 4366 didn’t exist days ago—now it’s nearly 10× wider than Earth and already fired off a triple-peaked M7–X1–M6 solar flare lasting over 6 hours. Its unstable magnetic field means more flares are likely. A radio blackout followed… and space weather may not be done yet. Track it live: https://spaceweather.com/ #Sunspot #SolarFlare #SpaceWeather #Sunspot4366 #XClassFlare #Astronomy
