Weyl semimetals with broken time reversal symmetry are difficult to identify unambiguously. In this work, using angle-resolved photoemission spectroscopy, we visualized the electronic structure of the ferromagnetic crystal $Co_3Sn_2S_2$ and discovered its characteristic surface Fermi-arcs and linear bulk band dispersions across the Weyl points. These results establish $Co_3Sn_2S_2$ as a magnetic Weyl semimetal that may serve as a platform for realizing phenomena such as chiral magnetic effects, unusually large anomalous Hall effect and quantum anomalous Hall effect.
