Scientific paper

VLA observations at 1.5 GHz with a resolution of 43arcsec are presented for the extended source 1253+275, located near Coma A (3C 277.3). The total size of the source is at least 25arcmin and its radio morphology is double, with very elongated and slighty misaligned lobes. Another much smaller double radio source with the axis roughly perpendicular to the overall structure is detected near the symmetry center of the large source, but its association with the extended source is unclear. No obvious optical identification is possible for the extended source. The authors suggest that it could be a relic radio galaxy, originated by the past activity of the close Coma galaxy IC 3900.
