Abstract

Multicolour time-series photometry of two newly discovered slowly pulsating sdB stars (V1093 Her stars, also known as PG 1716 stars) is described. Both stars are fairly bright and appear, from the limited amount of data, to have rich pulsation spectra. Given that the amplitudes of variation of both stars are also large compared to most PG 1716 stars, both are good candidates for extensive follow-up observations.
