Apparent motion of plasmoid-like blobs. The pink line in the large Hα wing image to the left traces the trajectory of some bright blobs. The st diagram for this trajectory is shown in the bottom right. The column of smaller images shows three different time steps; colored crosses mark the moving blob for which the respective spectral profiles are shown in the top-right panel. This blob has an apparent speed of about 55 km s⁻¹, a speed that is indicated by a straight pink line in the st diagram. The pink profile in the top-right panel is a reference EB profile that is marked with the large pink cross in the large image to the left. The cross is near the origin of the trajectory for the st diagram. The gray profile is a reference profile that was constructed by averaging over the full FOV.
