Abstract: We present the preliminary results of an ongoing photometric campaign to search for possible pulsations among O-type hot subdwarfs (sdOs). Fast CCD photometry has already been obtained for about 20 targets. A clear evidence of the presence of pulsations has not been obtained so far. We recommend 4 objects for re-observation.
