Abstract Fringes were detected throughout experiment on all 3 baselines (including 2 ground-space baselines). For ground-space baselines, good fringes were found for both NZ pass (16:00 -- 19:15 UT) and UZ pass (21:17 -- 23:00 UT). Both imaging and modelfitting went very well even though only 3 baselines were available. Calibration source (2145+067) was observed about 18 min and, detected with a correlated flux density of 1.4Jy on the ground baseline (Mop-Seshan25, 6,700km).
