Radio observations revealed a bright arc with an index of $\\sim -0.40$, which stands in contrast to the index of $\\sim -0.69$ for the rest. This arc is coincident with the point-like \\emph{Fermi} source 4FGL J0426.5+5434 and KM2A source 1LHAASO J0428+5531. The rest of the SNR has a hard GeV spectrum and a soft TeV spectrum, implying a spectral cut-off or break near 1 TeV.
