The Sun Today Join me for today's detailed solar activity update for March 16, 2025. Discover what's happening on our dynamic Sun, including sunspot groups, solar flares, solar wind conditions In this video, I cover: ☀️ Current Sunspot Activity: 13 active sunspot regions visible, including the notable AR 4019 with complex magnetic conditions (beta-gamma-delta). 🚨 Solar Flares: Today's strongest solar flare was a C4.0-class event—learn what this means for Earth and our satellites. 🌌 Coronal Mas

• Sunspot Light-Bridges • A Bridge from the Photosphere to the Corona? Light-bridges are lanes of bright material that divide the umbra in a sunspot. They are often observed during the break-up of sunspots and therefore can represent the re-establishment of convection which is normally inhibited by the sunspot's strong magnetic field. Their increased brightness suggests a higher plasma temperature than in the surrounding umbra, and they have been shown to display significantly enhanced chromosph
