Abstract

Abstract A distribution of the meter-wave luminous objects, which are bright at the frequency 74MHz (a wavelength of 4m), but not detectable at 1.4GHz (21cm) in VLA surveys, shows a notable concentration on a scale of a few degrees in the direction of Monoceros [($l$, $b$) $=$ (225$^{\circ}$, 4$^{\circ}$)]. We argue that it is a part of giant radio relics associated with a nearby cluster of galaxies with $c$z$\sim$ 2400kms$^{-1}$ centered on the spiral galaxy NGC 2377. The angular separation of these objects from the clustering center is consistent with the separation of distant relics from the cluster center if scaled by distance. This fact implies that the concentrations of meter-wave luminous objects can be used as a tracer of the structure of the Local Supercluster and its vicinity.
