VLBI hybrid maps are presented at 18 cm wavelength of the nucleus of M87 at epochs 1980.12 and 1982.27. The differences between these two maps are very slight. Internal proper motions at a 2 sigma confidence level of 0.3 c could not be detected. For a relativistic beaming model in which one sees the same material radiating at both epochs, the outflow velocity must exceed about 0.6c and the jet must be aligned to better than 12 deg with respect to the line of sight. If outflow velocities near the speed of light are assumed, then the alignment must be better than 1 deg.
