- Аннотация: Manifestations of the activity of the YZ CMi (M4.5Ve) flare star with a rotation period of 2.77 days, which is included in the group of activity-saturated stars, are considered based on long-term photometer data, including photographic measurements over the interval from 1926 to 2009. Long-term changes in the average annual star brightness found within the scale of 27.5 years with an amplitude of 0.2–0.3 reveal variations in the development of surface inhomogeneities and a greater degree of spotting at maximal activity. The spots are distributed unevenly over the surface with an increased concentration at certain longitudes spaced by intervals equal to 0.6 phases of the rotation period. The recovery of the active longitude (a possible “fliр-flop” effect) occurs over a period of about 6 years. The activity is different from that typical for the Sun and solar-like stars, which is associated with its dynamic characteristics P_cyc and P_rot and its inner structure.
