The recently discovered radio pulsar
PSRB 1259-63 has a 10th magnitude Be star companion
SS2883. Because the pulsar is in a wide eccentric
orbit it will be many years before pulsar timing
measurements will be able to determine its proper
motion across the sky. However, the companion
star SS2883 is relatively bright and its position
has been recorded in star catalogues up to 100
years old. Thus the proper motion of the system
may be determined from the optical motion of
SS2883. This new project will provide information
on the processes of formation of this binary
system and its place of origin
