Following evidence for an east--west elongated virial ring around the Comagalaxy cluster in a $\sim220$ GeV VERITAS mosaic, we search for correspondingsignatures in $>$GeV $\gamma$-rays from Fermi-LAT, and in soft, $\sim0.1$ keVX-rays from ROSAT. For the ring elongation and orientation inferred fromVERITAS, we find a $3.4\sigma$ LAT excess, and detect ($>5\sigma$) the expectedsignature in ROSAT bands R1 and R1+R2. The significances of both LAT and ROSATsignals are maximal near the VERITAS ring parameters. The intensities of theROSAT, Fermi, and VERITAS signals are consistent with the virial shockdepositing $\sim0.3\%$ (with an uncertainty factor of $\sim3$) of its energyover a Hubble time in a nearly flat, $p\equiv - d\ln N_e/d\ln E\simeq2.0$--$2.2$ spectrum of cosmic-ray electrons. The sharp radial profiles of theLAT and ROSAT signals suggest preferential accretion in the plane of the sky,as indicated by the distribution of neighboring large-scale structure. TheX-ray signal gauges the compression of cosmic-rays as they are advected deeperinto the cluster.
