  In the course of our survey of the outer halo of the Andromeda Galaxy we have
discovered a remote, possible satellite of that system at a projected 162 kpc
(11.7 degrees) radius. The fairly elongated (0.31 +/- 0.09 ellipticity) dwarf
can be fit with a King profile of 1.07 kpc (d/784 kpc) limiting radius, where
the satellite distance, d, is estimated at ~630-850 kpc from the tip of the red
giant branch. The newfound galaxy, ``Andromeda XIV'' (``AndXIV''),
distinguishes itself from other Local Group galaxies by its extreme dynamics:
Keck/DEIMOS spectroscopy reveals it to have a large heliocentric radial
velocity (-481 km/s), or -206 km/s velocity relative to M31. Even at its
projected radius AndXIV already is at the M31 escape velocity based on the
latest M31 mass models. If AndXIV is bound to M31, then recent models with
reduced M31 virial masses need revision upward. If not bound to M31, then
AndXIV is just now falling into the Local Group for the first time and
represents a dwarf galaxy that formed and spent almost its entire life in
isolation.
