The galactic superluminal transient X-ray source GRS 1915+105 was observedwith the pointed proportional counters (PPCs) onboard the Indian satelliteIRS-P3 during 1996 July 23-27. We report here details of the behavior of thissource during the relatively quiet and low luminosity state. Large intensityvariations by a factor of 2 to 3, generally seen in black-hole candidates, areobserved at a time scale of 100 ms to few seconds. No significant variation isdetected over larger time scale of minute or more. The intensity variations aredescribed as sum of shots in the light curve, and the number distribution ofthe shots are found to be exponential function of the fluence and duration ofthe shots. The cross correlation spectrum between 6-18 keV and 2-6 keV X-raysis found to have asymmetry signifying a delay of the hard X-rays by about 0.2to 0.4 sec. This supports the idea of hard X-rays being generated by Comptonup-scattering from high energy clouds near the source of soft X-rays. Verystrong and narrow quasi periodic oscillations in the frequency range 0.62 to0.82 Hz are observed. We discuss about a model which explains a gradual changein the QPO frequencies with corresponding changes in the mass accretion rate ofthe disk.Comment: 14 pages including 6 figures.
