Sunstorm was a heliophysics and space weather monitoring technology demonstration CubeSat satellite by the European Space Agency. During its three-year mission in the low Earth orbit, Sunstorm successfully tested a miniaturised X-Ray Flux Monitor instrument by observing solar flares. It was launched in 2021 on a Vega rocket and reentered the atmosphere in 2024.
