Quasi-simultaneous images of the Sun taken on November 2, 1998, in H I 121.6 nm (left) and He II 30.4 nm (center, right). The Lyman-α image was obtained by the rocket-borne MXUVI instrument at 18:20 UT. The 30.4 nm image was recorded by EIT at 18:26 UT. The EIT image was degraded to match the resolution of the MXUVI. Solar north is up. The intensity scales are logarithmic in both cases, and the contrast is the same. There is a remarkable morphological similarity for all types of structures, but, as is also visible in Fig. 4, they are less contrasted at Lyman α. In the right image, we overlaid different contours corresponding to different solar regions: active regions (red), filaments (green), the coronal hole (yellow), and prominences (purple).
