Positions of the active regions in 2015 from our four-spot model fit to the K2 C5 data (top row) and in 2018 from a two-spot model to the ground-based data (middle row) and from a four-spot model to the K2 C18 data (bottom row). The surface maps from left to right show the stellar hemispheres at primary minimum, first quadrature, secondary minimum and second quadrature, respectively.
