Time profiles of magnetic properties of AR11618 in the same layout as Fig. 3. (a) Total unsigned magnetic flux, unsigned connected magnetic flux used in the CB-based method, and X-ray flux from the GOES 1−8 Å channel (black, yellow, and maroon curves, respectively). (b) Free magnetic energy. (c) Right-handed, left-handed, and net helicity (red, blue, and black curves, respectively). (d) Magnetic energy injection rate, the corresponding accumulated energy, ΔE, and the total energy from the CB method (black, cyan, and purple curves, respectively). (e) Helicity injection rate and the corresponding accumulated helicity, ΔH, (black and green curves, respectively).
