Emission of the Hα line wings for a slit perpendicular to the event, highlighting the small-scale structuring within the events. (Top row) Time-distance plots taken for a slit across the event in the blue wing (left) and red wing (right). We emphasize the threads in this plot by enhancing the contrasts of the image. A black slit is over-plotted to indicate the region plotted with respect to intensity (bottom row). Note, the quadruple intensity minima between 1′′ and 2.5′′ indicated by the arrows.
