Abstract: In August 1994 EGRET has detected a strong gamma-ray flare (an order of magnitude above quiescent state) the source of which was identified with NRAO 190. During 1995-97 we have obtained 6 images of NRAO 190 with VLBA at 1 cm and 7mm which display a fairly bright core, a weak stationary component and a bright knot moving outwards with an apparent velocity of about 13c. The time of birth of that knot may be extrapolated to the date of gamma-ray flare. We discuss observed morphological and flux variability in the frame of shocked relativistic jet model.
