Chromospheric plage observation. The datasets were acquired with CHROMIS at the Swedish 1 m Solar Telescope and with NASA’s IRIS satellite on 2016-09-14 at 09:06 UT. Upper-left panel: CHROMIS field-of-view where the IRIS raster scan has been indicated. Three upper rightmost panels: overlapping FOV for a given time-step in the core of the Si IV 1400 Å line, the Mg II k line, and the Ca II K line. The colored crosses indicate the location of example spectra, shown in the bottom row with the same color coding for each line.
