  The wide-field CCD camera at the CFH telescope was used to survey the giant
stellar stream in the Andromeda galaxy, resolving stars down the red giant
branch in M31 to I ~ 25, a magnitude deeper than our previous INT survey of
this galaxy and extending 1 degree further out. The stream is seen to extend
out to the south-east of M31 as far as we have surveyed (some 4.5 degrees,
corresponding to a projected distance ~60 kpc). It is a linear structure in
projection, and the eastern edge of the stream presents a sharp boundary in
star counts suggesting that it remains a coherent structure. By analysing the
luminosity function of the metal rich component of the stream we find that, at
the furthest extent of our survey, the stream is 100 kpc further away along the
line of sight than M31. It can then be traced to a point on the north-western
side of the galaxy where it is some 30 kpc in front of M31, at which point the
stream turns away from our survey area.
