Abstract
The discovery observations of two new slowly pulsating subdwarf B stars (V1093 Her stars),
BPS CS22890−74 and PB 7032, are presented. Both stars are highly multiperiodic, and have –
for V1093 Her stars – large amplitudes. Published descriptions of the (wavelength) spectra
of the stars conflict, but new spectra show that both are sdB stars with effective temperatures
below 30 000 K. BPS CS22890−74 has a cool companion.
