Photospheric and coronal overview of the active region NOAA 12297 on 12 March 2015. Panel a: white-light image. The black oval encircles a few small, distinct sunspots. The blue arrow indicates the most prominent sunspot group of the active region. The red arrows indicate a few narrow, elongated umbrae within the major sunspot group. Panel b: co-temporal magnetogram. The sky-coloured arrows indicate two localised magnetic patches within regions of opposite polarity. For correlation, we have plotted two sky-coloured arrows in panel a at exactly the same locations as the sky-coloured arrows in panel b. Panels c–d: EUV images in the AIA 171 and 131 Å channels, respectively. The deep-blue arrows in panel c and pink arrows in panel d indicate an interesting set of coronal loops (also marked ‘QL’ in panel c) which appear similar to quasi-separatrix layers (QSLs). The green arrows in panels c and d indicate another interesting set of coronal lines (also marked ‘FS’ in panel c), which appear similar to a fan-spine configuration. The sky-coloured arrows in panel c indicate two localised bright kernels, which are exactly co-spatial with the magnetic patches indicated by sky-coloured arrows in panels a and b. Co-temporal LOS magnetogram contours are overplotted in panel d. Contour levels are ±[500, 2000] G. Red and yellow contours refer to positive and negative magnetic flux, respectively.
