Caption: Magnetic field on the solar surface and the initial brightening of largest solar flare (GOES class X9.3) in the solar cycle 24 in NOAA Active Region (AR) 12673 on Sep. 6, 2017. They were observed by HMI and AIA onboard the NASA’s Solar Dynamics Observatory (SDO) satellite. A: Magnetic field on the solar surface before the onset of the large flare at 11:45 UT on the day. White and black indicates the intensity of magnetic field along the line of sight out of and toward the plane. B: The zoom-in view of vertical magnetic field in AR 12673. A white circle indicates the location where a large flare was predicted by this study. Black contour shows the magnetic polarity inversion (PIL). C: Bright flare ribbon observed by SDO/AIA1600Å at 11:52 UT. B and C are reformatted based on Fig.3 of this research paper by Kusano et al. (2020) published in Science.
