cds-question@unistra.frhorizontal-branch-starssubdwarf-starsWe present the results of 215h of time-series photometry on the rapidly pulsating subdwarf B star PG 1325+101 (T_eff_=35000K, logg=5.8, logN(He)/N(H)=-1.7), obtained during 25 days of observation in Spring 2003 from nine different sites. As in previous observations, the temporal spectrum is dominated by the main peak at 7255.55{mu}Hz, with an amplitude of about 2.7% which, however, is dropped to about 1.7% in February 2005. No secondary peaks close to the dominant pulsation mode are clearly detected. In addition, at least fourteen more pulsation frequencies are found: three of them at 7704.92, 9380.17 and 14511.10{mu}Hz were already present in the discovery run with small differences in frequency, probably due to 1-day aliasing effects. The peak at 7704.92{mu}Hz belongs to a triplet of almost equally spaced frequencies that could be due to rotational splitting and would imply a rotational period of about 1.6 days. Based on the results of this article, a detailed asteroseismic analysis of PG 1325+101 is presented in a separate paper (Charpinet et al., 2996A&A...459..565C, Paper II).2006A&A...459..557Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/459/557CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/459/557https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/459/557http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/459/557https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/459/557https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/459/557http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/459/557GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/459/557/lcwhole*PG1325+101 relative fluxesrecnoRecord number assigned by the VizieR team.
