We report the discovery of the radio and infrared counterpart of the hard X-ray transient GRS1915+105 in the constellation of Aquila. The compact object is located beyond approximately 30 magnitudes of optical absortion. At radio wavelengths it exhibits drastic time variations in flux which are correlated with changes in the hard X-rays. The source also shows unusual variability in the H(1.65 micrometers) and K(2.2 mircometers) infrared bands. We propose that in the course of its slow rise to maximum intensity, GRS1915+105 may have triggered three soft gamma-ray bursts of short duration that were observed from the same region of the sky during June-August 1992.
