We report on the discovery and hard X-ray (20È70 keV) observations of the 4.45 s period transient X-ray pulsar GRO J1750[27 with the BATSE all-sky monitor on board CGRO. A relatively faint outburst (\30 mcrab peak) lasting at least 60 days was observed during which the spin-up rate peaked at 38 pHz s~1 and was correlated with the pulsed intensity. An orbit with a period of 29.8 days was found. The large spin-up rate, spin period, and orbital period together suggest that accretion is occurringdoi:10.1086/304740 fatcat:djymdljs6fazdaglnm3fulq3oe
