Close-up on the northern leg of the loop bundle showing long-period EUV pulsations. RGB images at different steps of the SST sequence. For each step we show a combination of the AIA 304 Å channel in blue, one position in the red wing (+0.80 Å) of the Hα line in green, and one position in the red wing (+0.45 Å) of the Ca II K line in red. Path 1 is displayed as a context for Fig. 9. An animation of this figure is available online.
