X8 (super)Flare and Supra-Arcade Downflows (SADs) • AKA Coronal Tadpoles Supra-arcade downflows (SADs) are sunward-traveling plasma structures that are sometimes observed in the Sun's outer atmosphere, or corona, during solar flares. These enigmatic plasma structures often appear like dark-colored "tadpoles swimming" downward in a bright fan region above an arcade of post-flare loops in the corona. The physical nature of such structures remain elusive. Detecting them with a slit spectrometer wou

Earth-directed Coronal Mass Ejection from Sun | NASA’s SDO FriendsofNASA.org: The Sun emitted an Earth-directed coronal mass ejection (CME) on July 21, 2024. NASA’s Solar Dynamics Observatory (SDO), watching the Sun constantly in extreme ultraviolet light, captured images of the event (see brief, bright flash at upper left). A CME is an eruption of solar material. When they arrive at Earth, a geomagnetic storm can result. A G2 geomagnetic storm watch has been issued. Watches of this level are un
