• IRIS • Solar Explosions and Loop Arcades 6.6.2020 • Taken over a three hour period in 2015 by NASA/IRIS (Interface Region Imaging Spectrograph) these loop arcades are highly dynamic structures that suspend solar plasma thousands of kilometers above the surface against the force of gravity. They can be disrupted during eruptions and part of plasma falls back onto the Sun. Understanding how they are formed and what drives the eruptions is still a great challenge. Supra-arcade downflows (SADs) ar
