Abstract: We measured relative positions of the 22 GHz H_2O maser components toward the class 0 protostar S106FIR with the VLA. Two clusters of H_2O masers were found. The separation between these clusters is approximately 50 AU at position angle (=73 degrees) and each cluster is spread over about 10--20 AU The size of the S106FIR maser clusters is unusually compact compared with other known H_2O masers associated with outflows of forming stars. The maser emission appears to originate from MHD driven outflow very close to the star.
