  Edge supercurrents in superconductors have long been an elusive target.
Interest in them has reappeared in the context of topological
superconductivity. We report the observation of a robust edge supercurrent in
the Weyl superconductor MoTe2. In a magnetic field B, fluxoid quantization
generates a periodic modulation of the edge condensate observable as a
"fast-mode" oscillation of the critical current Ic versus B. Remarkably, the
fast-mode frequency is distinct from the conventional Fraunhofer oscillation
displayed by the bulk supercurrent. We confirm that the fast mode frequency
increases with crystal area as expected for an edge supercurrent. In addition,
weak excitation branches are resolved which display an unusual broken symmetry.
