Abstract Strong fringes were detected on most ground-ground baselines except those to Mop and Hobart. Mop also had problem with amplitude gains which can be seen from both survey source and calibration source data. Hobart gains were multiplied by a factor of ~0.6 to match the adopted DPFU of 0.1 and the measured Tsys of ~300K. For ground-space baselines, good fringes were detected during the entire GZ pass (14:58 -- 18:16 UT). Imaging with DIFMAP showed a compact central component with some possible emission to the south. To keep simple, a circular Gaussian component model was adopted to fit the calibrated data of the survey source J1658+07. The calibrator 1253-055 has a correlated flux density of 5.1 Jy on the baseline HARTRAO-HOBART of 9,000 km.
