| 英文摘要 | We present three epochs of VSOP observations of the BL Lac object 2007+777 at 5 GHz. Compared with the ground-based VLBA data, the space baselines with HALCA cleasly reveal a more detailed and finer source structure. Mainly based on the quite uniform and circular UV-coverages of the VLBA, and using a new cross-selfcalibration method, we have found evidente for weak structural changes on a timescale of two weeks in the core region of this intraday variable source. The physical causes for these variations are discussed. |
