The Sun: Abundant Sunspot Activity | NASA’s Solar Dynamics Observatory FriendsofNASA.org: An abundance of sunspot groups are present on the visible solar disk—at least 12 active regions. Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. Solar flares are a sudden explosion of energy caused by tangling, crossing, or reorganizing of magnetic field lines near sunspots. The southern solar hemisphere has the m

🌞 📰 Sun news August 4: Large sunspot region rotating into view 😮 🤩A large new sunspot region has begun to rotate into view. Another one (seen via helioseismology) in the northeast is not yet visible but has already released a moderate (M5.5) flare from over the limb (edge). Because it is not yet in view, this flare was more than likely much larger. 👏 😎 This could mean another round of higher activity is coming. The M5.5 flare came about one hour after an M7.3 from region AR3775. This type

This is the biggest sunspot we’ve seen in almost a decade! 🤩 ☀️ Sunspots are cooler, darker areas on the solar surface where the Sun’s magnetic field gets especially intense, often leading to explosive solar eruptions. This sunspot was so big that nearly 14 Earths could fit inside it! The eruptions from this sunspot resulted in the historic May 2024 geomagnetic storms, where the aurora borealis, or northern lights, were seen as far south as the Florida Keys.

Looking at the coming sunspot via video. SDO detects vibrations of the Sun that allows us to "see" the other side - this is called helioseismology. The left globe is on the other side of the Sun, and the right one is the Earth-facing side of the Sun. The yellow-green shows magnetic field of the sunspot regions. Cool! 🌞😃✨ | The Sun Today: Solar Facts and Space Weather
