Difference in the evolution patterns of adjacent loops. Panels (A) and (B) showcase snapshots of the AIA 171 Å and HRI_EUV passbands, respectively, at 04:21:09 UT. Panel (C) shows the color-coded light curves for the boxes marked in panels (A) and (B). Procedure to calculate light curve is described in the caption of Fig. 2. The box size for loop 1 in AIA and HRI_EUV are increased to 9 × 9 and 36 × 36 pixel, respectively.
