Fig. 1.


Photospheric (SDO/AIA 1700 Å; panel a) and TR (IRIS SJI 1400 Å; panel b) images of the ROI (plage region). The plage is seen as high-intensity patches clearly visible in the photosphere and in TR (panels a and b). We show the absolute LOS magnetic field (panel c) and magnetic field inclination map (panel d) of the same region using SDO/HMI observations. A high magnetic field and low inclination angles are visible in the vicinity of the plage area. The plage locations were selected using a threshold of absolute magnetic field (i.e., above 300 gauss) and locations are contoured (i.e., above 300 gauss) over magnetic field inclination (panel d) in green, which reveal the presence of almost vertical (or very low inclination) fields.
