In this article we present the first results of about 95 hours of time-series photometry on the low gravity sdB pulsating star HS 2201+2610, obtained from a multi-site time-series campaign in September-October 2000. The temporal spectrum of HS 2201+2610 shows 3 close frequencies at 2860.9, 2824.1 and 2880.8 μHz with amplitudes of about 1 %, 0.4 % and 0.1 % respectively. Due to the small number of excited modes, a mode identification is possible in principle but not easy; no clear signatures of rotational splitting are seen.
