SPICE rasters in the C III line (log T = 4.8 K) over a region that overlaps with region 4 on April 1st. The FOV corresponds to the red rectangle to the east shown in Fig. 2 (bottom), and the overlaid red curves denote some of the rain paths seen with HRI_EUV (see Figs. 10 and 11). The HRI_EUV panel corresponds to an SR matching the time of the first SPICE raster (see the text for details), but preserving the HRI_EUV spatial resolution. The SPICE panels show the total intensity integrated over the C III spectral line for each raster (the time is shown in the subtitle).
