... The source exhibits a mas-scale structure which, according to the USNO multi-epoch monitoring at 2.3 and 8.4 GHz over the period from 1994 July through 1998 April, undergoes considerable changes in the brightness distribution and positions of the major structural features. Our image is qualitatively consistent with the structural pattern of the source. ... We note a difference of ~90 in position angles of secondary components in our image and the 5 GHz VLBI image by Shen et al. 1998). ...
