Overview of IRIS raster field of view. The individual panels represent (a) the total intensity of the Si IV 1394 Å emission line obtained from IRIS, (b) one image from AIA in the 171 Å channel observed near the midpoint of the IRIS raster, (c) the rastered line-of-sight magnetogram constructed using data from HMI, which is nearly cotemporal with the IRIS raster (see Sect. 2.2), and (d) the Si I Lyman continuum obtained from IRIS around 1395 Å. Panels a and b are plotted in logarithmic scale. The black and white contours in panels a and b outline the magnetic field from panel c at values of −30 G and +30 G, respectively. The red contours in all panels outline the brightenings in the continuum intensity from panel d. The three white squares and green arrows in all panels highlight different features, as discussed in Sects. 2.2 and 3.1.
