Scientific paper

Observations of the source are presented and examined in terms of the existence of a discrete radio source and of the possible connection with other emission in the Coma cluster. High-resolution data are taken from multifrequency observations from the VLA to look for discrete sources or active objects and from the Westerbork Synthesis Radio Telescope for high-resolution extended low-brightness emission. The data are interpreted to bar from consideration the discrete compact radio source, but they indicate a relationship between the source and the Coma cluster emission. The source 1253 + 275 is diffuse with a central ridge that connects the cluster galaxy NGC 4789 with a SW leading edge. A relationship is inferred between the central halo Coma C and the diffuse emission located between Coma C and the object 1253 + 275.
