We have mapped the nearby (z=0.018), active galaxy NGC 1275 (3C84) at 6 different epochs from 1981 to 1986 at 1.3 cm (22.3 GHz) with a global VLBI array of seven telescopes. We find a long-lived knot of emission separating from the brightest radio component with a projected velocity = 0.4 6±0.12 h−1 c. This knot moves through diffuse emission that also moves away from the main component with a slower projected velocity of 0.33±0.12 h−1 c. We show that the knot and diffuse emission result from two separate events that occurred around 1959 and 1968.
