NST/VIS Hα – 0.8 Å images of the X1.6 flare on 2014 November 7 during the early phase. The arrows in the lower panel indicate sites of initial flare brightenings associated with the P1 and N1 umbrae. The blue/yellow contours represent 17:00 UT HMI vertical positive/negative fields plotted at ±50, ±500, ±800, and ±1100 G. The FOV is 22″ × 6″ and corresponds to the yellow box in Figure 2. The images were not corrected for the projection effect.
