Time evolution of the observed and predicted axial dipole moment. The thick lines indicate the observed axial dipole moment (black: WSO, red: MDI, green: HMI). The thin lines indicate the prediction by the SFT without introducing new emerging flux starting from the observed synoptic magnetogram. The dotted lines indicate the timing of the cycle minimum. The minimum in Cycle 24 is assumed to be in 2020.
