Further interferometric observations were made of the radial velocities of faint filaments in the central region of the optical supernova remnant IC 443. Individual filaments in this nebula are moving at a velocity of 160 to 170 km/sec, or three times as rapidly as the mean expansion velocity of the envelope previously estimated. The corresponding age of IC 443 is 25,000 yr. The compatibility with current views regarding shock propagation in supernova remnants is discussed.
