Representative examples of space-time (x-t) maps derived from the HRI_EUV (panel a), AIA 171 Å (panel b), and AIA 193 Å (panel c) image sequences. Zoomed-in versions of these maps, between t = 30 min and 40 min, are presented in panels a.1, b.1, and c.1, respectively. The arrows in these zoomed-in panel point to the slanted ridge that is created by the thin strand. The vertical dotted lines in these panels outline the shift of the loop as judged visually.
