Comparison between consecutive CRs. The left panels show the solar wind velocity taken from ACE for the respective CRs while the right panels show the PFSS model data of the photospheric foot points of the open magnetic field line. The latter rotations 2055 and 2050 are shown in red, the former rotations 2054 and 2049 are shown in blue. The upper panels show the case for CR 2055, where the predictions produced very good results while the lower panel show the case for rotation 2050, where only very poor results were produced.
