We present some recent VLBI images of the two BL lac objects OQ 530 and ON 231 obtained with the European VLBI Network (EVN) facility. OQ 530 is c haracterised by a well structured jet, extending more than 30 mas at P. A. about 120 degrees. ON 231 shows a jet elongated in the east direction, but on the opposite side a new component at a distance from the core of about 2 mas was discovered by Massaro et al. (2001). The additional images presented in this contribution show that this new component was already detectable in May 1997.

Abstract

We present some recent VLBI images of the two BL lac objects OQ 530 and ON 231 obtained with the European VLBI Network (EVN) facility. OQ 530 is c haracterised by a well structured jet, extending more than 30 mas at P. A. about 120 degrees. ON 231 shows a jet elongated in the east direction, but on the opposite side a new component at a distance from the core of about 2 mas was discovered by Massaro et al. (2001). The additional images presented in this contribution show that this new component was already detectable in May 1997.
