OBSERVATIONS OF THE TRANSIENT-X-RAY PULSAR GRS 0834-43 IN ITS LOW STATE WITH THE INSTRUMENTS OF THE ROENTGEN OBSERVATORY ON BOARD THE MIR-KVANT MODULE IN NOVEMBER 1992

A series of observations of the transient X-ray pulsar GRS 0834-43 was carried out with instruments Of the ''Roentgen'' orbital observatory on board the ''Kvant'' module during the period of the expected outbur st from November 1-24, 1992. No luminosity increase of the object was registered in our observations. The flux of the source remained on the level 20-30 mCrab corresponding to the flux between outbursts. The ob tained spectrum of the source in the 2-100 keV range is typical of X-r ay pulsars in binary systems. It is remarkable that there are no notab le differences in the pulsar's spectrum between its low state (this pa per) and its high state (''Granat'' satellite data [4]), though the lu minosity of the source was different by a factor greater than 5.
