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±0.2)h-1 and (5.1±0.3)h-1. 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.
