The discovery of a giant debris arc in the Coma Cluster

Abstract
We present the discovery a giant low surface-brightness arc, of length luminous matrix with surface-brightness mu_B < 26.5 mag arcsec^{-2} and a number of embedded condensations. It is not associated with any giant galaxy in Coma in particular; neither does it have the properties of a gravitational arc. We argue that a fast interaction between the nearby barred S0 galaxy IC 4026 and either IC 4041 or RB 110 is the most natural explanation for the origin of the arc.
