ACCRETION INSTABILITIES AND JET FORMATION IN GRS-1915+105

We report simultaneous observations in the X-ray, infrared, and radio wavelengths of the galactic superluminal source GRS 1915+105. During e pisodes of rapid disappearance and follow up replenishment of the inne r accretion disk evidenced by the X-ray oscillating flux, we observe t he ejection of relativistic plasma clouds in the form of synchrotron f lares at infrared and radio wavelengths. The expelled clouds contain v ery energetic particles with Lorentz factors of similar to 10(3), or m ore. These ejections can be viewed as small-scale analogs of the more massive ejecta with relativistic bulk motions that have been previousl y observed in GRS 1915+105.
