Based on resolved stellar photometry from the Sloan Digital Sky Survey, we recently reported the discovery of Andromeda IX, a new dwarf spheroidal satellite of M31 that is the lowest luminosity, lowest surface brightness galaxy found to date. We have been carrying out an extensive program of followup observations, using telescopes ranging from the 2.5m NOT to the 8m Gemini North. We present early results of our work to learn more about Andromeda IX, as well as of our search for more ultra-low luminosity satellites of the Andromeda Galaxy.
