1458+718(4C +71.15, 3C 309.1, NRAO 464)QSO z= 0.905 V= 16.78
Notes (from the published papers):
4C\,71.15, 3C\,309.1, NRAO\,0464 or 1458+718 has $V$=16.78
and $z$=0.905. It is one of the most prominent compact
steep spectrum radio sources (\citet{VanBreugel84},
\citet{Fanti95}.
%\citet{Kus90} studied
%this source at XX\,GHz and identified four components
%out to 50\,mas from the core.
\citet{Aaron97} and \citet{Aaron98} studied the polarization
and multifrequency properties of this radio source at pc-scales in
detail.
Our map from August 1997 reveal a compact core and a more
extended component 20\,mas to the South, with some extended,
diffuse emission out of this one. Lower frequency maps show
emission connecting those two big features and further out up
to 50\,mas and then turning to the East.
