Overview of the observations taken on 2016-09-15 at 08:57:02 UT. (a) Continuum intensity at 4000 Å; (b) wavelength-averaged circular polarisation map based on the Stokes V signal in the Fe I 6301 line; (c) wavelength-averaged linear polarisation map based on the Stokes Q and U signal in the Fe I 6301 line; (d) Ca II 8542 Å nominal line centre intensity; (e) Hα nominal line centre intensity; (f) Ca II K nominal line centre intensity. Panels d and f have been gamma-corrected to increase visibility of the structures present in the images.
