Left: changing longitudes of spots of TIC 271892852 in time. Red and blue circles result from time-series photometric modeling and eclipse mapping, respectively. The shade of the blue circles reflects the contrasts of the spots from eclipse mapping. Note that the x-axis of the figure covers one stellar circumference in longitude. Gray shading shows the longitudes scanned by the companion star. Three arrows mark the rotations with fitted spots whose eclipses are shown in the right panel. Right, from top to bottom: example eclipse fits revealing spots scanned already during ingress, just in the middle of the eclipse, and during egress.
