Description
We have gathered and analysed a timeseries of 1493 high-quality
multicolour Geneva photometric data of the B3V {beta} Cep star Hd
129929. The dataset has a time base of 21.2 years. The occurrence of a
beating phenomenon is evident from the data. We find evidence for the
presence of at least six frequencies, among which we see components of
two frequency multiplets with an average spacing of ~0.0121c/d which
points towards very slow rotation. This result is in agreement with new
spectroscopic data of the star and also with previously taken UV
spectra. We provide the amplitudes of the six frequencies in all seven
photometric filters. The metal content of the star is Z=0.018+/-0.004.
All these observational results will be used to perform detailed seismic
modelling of this massive star in a subsequent paper.
