Image of a solar active region from full-disk observations taken on 20 April 2015 with VSM/SOLIS. Background images correspond to the continuum-normalized intensity in a) the wing and b) core of the Ca II 854.2 nm line and longitudinal magnetograms corresponding to c) the wing (photosphere) and d) core (chromosphere). The contours in all panels show the location of sunspots (white, intensity level of 5000 counts), the plage and enhanced network (blue, 5500 counts), and the brightest kernels in the plage (red, 5670 counts). The intensity images were normalized by a limb-darkening function derived directly from the observations. Each panel is about 580 by 537 arcseconds in size, centered on active region NOAA 12324. The background image in panel a is scaled between 2500 and 5800 counts (in comparision, the mean intensity at solar disk center is about 5409 counts). The background image in panel b is scaled between 1800 and 5180 counts (in comparision, the mean intensity at solar disk at line core is about 2670 counts). The magnetograms (background images in panels c) and d) are scaled between ±1000 G, with white corresponding to positive-polarity fields and black to negative-polarity fields.
