The quasar 3C 273 has been observed at 10.7 GHz at three epochs spanning 1984.1-1985.6. Two new superluminal components, C5 and C7a, are separating from the core with apparent transverse velocity v/c = (8.0 + or - 0.2)/h and (5.1 + or - 0.3)/h. The old components C3 and C4 may still be recognizable, with C4 having moved from 2.5 to perhaps 10 mas from the core in 7 yr. Nonmonotonic curvature near the core is confirmed. 8 references.
