  We present a possible orbit for the Southern Stream of stars in M31, which
connects it to the Northern Spur. Support for this model comes from the
dynamics of planetary nebulae (PNe) in the disk of M31: analysis of a new
sample of 2611 PNe obtained using the Planetary Nebula Spectrograph reveals ~20
objects whose kinematics are inconsistent with the normal components of the
galaxy, but which lie at the right positions and velocities to connect the two
photometric features via this orbit. The satellite galaxy M32 is coincident
with the stream both in position and velocity, adding weight to the hypothesis
that the stream comprises its tidal debris.
