We report the detection of short period oscillations in the hot subdwarf B (sdB) star PG 1613+426 from time-series photometry carried out with the 91-cm Cassegrain telescope of the Catania Astrophysical Observatory. This star, which is brighter than the average of the presently known sdB pulsators, with B=14.14mag, has T_eff=34400K and logg=5.97, its position is near the hot end of the sdB instability strip, and it is a pulsator with a well observed peak in the power spectrum at 144.18±0.06s. This star seems to be well suited for high precision measurements, which could detect a possible multi-mode pulsation behaviour.
