		| 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. |
