****************************************************** PR # 32094 GRS1915+105 is a hard X-ray transient discovered in August 1992. It showed a power-law energy spectrum in 40 -- 300 keV without a signature of high energy cut-off, exhibiting a common characteristic of black hole candidates. The outstanding feature of GRS1915+105 is the super-luminal motion of jets of material discovery by VLA. The velocity of the jets is estimated as much as 92 \% of the light velocity. The energy spectra in the 0.5 -- 10 keV band has hardly been studied. With ASCA observations, we will search for blue- and red-shifted iron emission lines from the hot relativistic bipolar jets, just as have been observed from SS433 with ASCA. ******************************************************
