AbstractIn this paper, the evolution history of longitudinal magnetic field of a decaying active region (NOAA AR6703) was studied. We also described the X1.9/4B flare occurring in AR6703, as well as the accompaning events, and emphasized in analysizing the features of longitudinal magnetic fields before the flare.
