Abstract: We report here the results of VLBA observations of Sagittarius A* (Sgr A*) at 43GHz, when Sgr A* showed an intraday variation. The flux density increased from 1Jy to 3Jy, and the duration is about 104 seconds which is quite similar to its X-ray flaring that Chandra detected. VLBA snapshot mappings show that Sgr A* flared and erupted jets in two opposite directions (north-south) with nearly half the speed of light. The lengths of jets reached about 15AU at most.
