The stability of the pulsation periods of the sdB pulsator HS 2201+2610 is analyzed after 15 months of photometric monitoring. Although the time basis is not long enough to obtain a measurement of P, an upper limit of about 4×10-12 (in absolute value) is derived for the variation of the main pulsation period in time.
