HRI_EUV intensity image of the area corresponding to the Hinode/EIS upflow region and its surroundings (Fig. 2). In panel a, the white contour highlights the re-projected ROI-A that corresponds to the Hinode/EIS upflow region with Doppler upflow velocities v < −5 km s⁻¹. The dashed black line highlights the location of the single-pixel-wide line used to measure the velocity along the loops. The extended loop is marked with a red arrow. The blue arrow shows a low-intensity area in the upflow region. Panel b shows a change in intensity along the extended loop with time obtained from HRI_EUV observations (see the profile line in the figure to the left). The red line is fitted to the locations with the highest intensity and has a velocity of 9.9 ± 0.4 km s⁻¹. All panels are scaled to the same intensity range (900−2300 DN/s). The footpoint of the extended loop has a Doppler velocity determined by Hinode EIS of −8.6 ± 2.3 km s⁻¹ (Fig. 2).
