Analytical spot model fitted to our CHEOPS data. Upper panel: CHEOPS light curve (black dots) with the fitted analytic spot model (blue solid line). Dashed lines denote the longitudes of the fitted spots while dash-dotted lines indicate the radii of these spots. Middle panel: residual after subtraction of the spot model. Lower panel: residual after subtraction of the low-order polynomial. Blue ticks denote the positions of the two observed flares. The light curve is phased following Eq. (1) with P_rot = 10.39 days.
