Example of the Hα line-center validation process for a Hα blue-wing-detected eruption. The top row shows Hα blue-wing images (taken at a wavelength of Hα − 0.8 Å) with the detected MFE and its evolution through time. The bottom row shows the corresponding Hα line-center image (taken at a wavelength of 6562.8 Å) at the same time. A nearby darkened feature within the matching radius confirms the eruption in both datasets.
