Overview of the solar flare on 2014 September 6. Panel a: light curves in GOES 1−8 Å (black), and Fermi 4−11 keV (red) and 11−26 keV (turquoise). The vertical line indicates the flare onset time, the dashed line outlines the beginning time of the non-damping oscillations. Panels b−f: SJI 1400 Å image, AIA 1600 Å image, HMI LOS magnetogram, and AIA 94 Å and 131 Å images. The purple contours are based on the intensity level of the SJI 1400 Å image, the HMI image saturates at ±500 G, and the AIA and SJI images are shown in a logarithmic brightness scale. Panel h: difference image in AIA 131 Å. The IRIS slit position is marked by blue dashed lines. The red boxes give the regions used in the DEM analysis. Two red bars enclose the flaring loop top used for further analysis. The temporal evolution over ∼34 min in AIA 94 Å and 131 Å is available as a movie, which also contains running difference images in the lower panels.
