ABSTRACT: We present recent 3mm-VLBI results on the Galactic Center using an array of four antennas. We find the closure phase measured around a triplet of antennas to be near zero. This places some constraints on the asymmetric structure of SgrA* along the position angles measured by our interferometer. We also discuss the problems and importance of calibration in VLBI measurements.
