Results for weak-field shifts from WSO synoptic maps. Top: weak-field shifts calculated for each latitude bin and rotation, called here the shift butterfly diagram (positive shifts in red, negative in blue). Middle: hemispheric shift values (north in pink, south in cyan). Bottom: longitudinal means of the photospheric field for each latitude bin and rotation, i.e., the normal magnetic butterfly diagram (positive field in red, negative in blue). Vertical lines denote the shift extrema (north in pink, south in cyan).
