0834-201

(OJ -257.5)
QSO
z= 2.752
V= 19.40

Notes (from the published papers): 0834-201 is a flat-spectrum blazar with $V$=19.4 and a $z$=2.752 (\citet{Hewitt89}). Pioneering VLBI observations were carried out on this radio source at 1.6\,GHz by \citet{Kellermann71}, reporting a compact structure within 10\,mas. The VLBA calibrator survey (\citet{Beasley96}) map at 2.3\,GHz shows a compact structure extended to the West. Our maps show a compact source with a very faint component at 4\,mas with a P.A.\ of $-100^\circ$.
