  We report simultaneous observations in the X-ray, infrared, and radio
wavelengths of the galactic superluminal source GRS 1915+105. During episodes
of rapid disappearance and follow up replenishment of the inner accretion disk
evidenced by the X-ray oscillating flux, we observe the ejection of
relativistic plasma clouds in the form of synchrotron flares at infrared and
radio wavelengths. The expelled clouds contain very energetic particles with
Lorentz factors of about 1000, or more. These ejections can be viewed as
small-scale analogs of the more massive ejecta with relativistic bulk motions
that have been previously observed in GRS 1915+105.
