Comparison of UFO and CME dynamics. Left: evolution of the UFO velocity (in black). Middle: evolution of the UFO acceleration (in orange). Both panels are overlaid with the XMM-Newton OM (blue), soft-band (gray), and hard-band (red) X-ray light curves. Right: schematic view of the early dynamic evolution of a typical CME event close to the Sun, adapted from Temmer (2016). We see that the UFO and CME patterns are similar to each other, with the acceleration phase aligning with the hard-band flare and the velocity correlating with the soft-band flare.
