Abstract: We present the preliminary results of more than 160 h of time-series photometry on the subdwarf B pulsating star PG 1325+101 (T-eff = 34 500 K log g = 6.1), obtained in March-April 2003 at nine different sites. The amplitude spectrum confirms the presence of the four frequencies found in the discovery run at the NOT in July 2001 ( but with significantly lower amplitudes in two of them) and also shows at least two new low amplitude signals. Moreover, there is no sign of frequency splitting near the main peak at 7256 muHz, suggesting that this mode might be actually radial as indicated by the time-resolved spectroscopy (Ostensen and Telting, 2004).
