(a) Accumulation of the magnetic helicity vs. time for NOAA 9182; (b) Number of patches identified in the map of the magnetic helicity flux vs. time; (c) Absolute value of the difference between the numbers of positive and negative patches vs. time. t = 0 corresponds to 00:00 UT of the initial day of MDI data set used in the analysis. The vertical lines indicate the flare occurrence. The thickness of the vertical lines is equal to 1–3 for flares of GOES C, M, and X classes, respectively. In red are indicated the flares associated with CMEs.
