Reconnected flux as compared with the profile of X-ray flux. (a) The GOES soft X-ray flux (1–8 Å) from 11:30 to 12:30, 2017 September 6. (b) Same as (a) but for a small interval of 5 minutes starting from the beginning of the flare. (c) The time derivative of the flux shown in (b). (c) The temporal evolution of reconnected flux in the simulation. (d) Time derivative of the reconnection flux curve, i.e., reconnection flux rate.
