Proper motion of IRC+10216 determined for epochs 1969.36 (Becklin et al. 1969), 1987.51 and 1993.07 (both Menten et al. 2006), and 2006.16 (this paper). The red and blue dots mark the position offset relative to the epoch 1987.51 position in the eastward (x) and northward (y) directions, respectively. The error bars for the 2006 position are comparable to the symbol size. Lines represents least-squares fits to the data. For the first two epochs the times have been slightly offset for clarity.
