Overview of the X1.6-class solar flare (SOL2014-09-10T17:45). (a) GOES-15 soft X-ray flux in the 0.5–4 Å (black) and 1–8 Å (red) channels. The vertical dashed line and colored arrows denote the onset of the hot-channel flux rope (HFR) eruption (blue) and the initiation of various reconnection jets, respectively. (b)–(d) Eruption of the HFR. Arrows in panel (c) indicate the slipping directions of the footpoints, while the red dashed circles highlight new magnetic footpoints during the eruption. (e) HMI line-of-sight magnetogram overlaid with contours of the flare ribbons during the HFR eruption, as recorded in AIA 1600 Å images at different times. (f) Spatial distribution of three groups of reconnection jets detected within the ambient coronal arcades outside the HFR. The red sigmoidal structure outlines the preeruption HFR, derived from the AIA 94 Å image at 17:00 UT. In panels (e) and (f) star symbols and colored arrows denote the initiation sites of reconnection jets (Jet-1 to Jet-3) and their ejection directions, respectively.
