EVN observations of the BL lac object 1219 + 285

Abstract

We present results of observations of the BL Lac objet 1219 + 285 with the European VLBI Network (EVN) at 1.7 GHz and 5.0 GHz. Our data reveal a misalignment of ∼60° between the radio structure of 1219 + 285 observed at these two frequencies. The lower resolution (∼20 mas) structure seen with the EVN at 1.7 GHz appears to be orientated in a direction intermediate between that of the inner VLBI jet and that of the outer VLA jet, indicating continuity of the jet from milliarcsecond to arcsecond scales.
