Abstract: We show that a general relativistic accretion flow, heated via the plasma wave heating mechanism, is consistent with the polarization and recent millimeter-VLBI observations of Sgr A* for inclination angle of ∼ 45°, position angle of ∼ 140°, and spin < 0.9. However, the parameters inferred from current observations depend significantly upon the adopted model. We then consider eight potential millimeter-VLBI stations, including the possible sites in Chile and New Zealand, finding that with these the basic geometry of the emission region can be reliably estimated.
