(a) A close-up view of the HRI_EUV region within the green box in Fig. 1(b), enclosing loop L1. The small boxes, each of size 5×5 pixels marked in different colors, are used to compute the light curves, which are plotted in the corresponding colors in (b). (c)-(d) Same as (a)-(b), but for loop L2. Notably, both L1 and L2 (blue curves) exhibit minimal variations in intensity during their evolution unlike their neighboring counterparts.
