  We report observations of the binary microlensing event OGLE-2018-BLG-0022,
provided by the ROME/REA Survey, which indicate that the lens is a low-mass
binary star consisting of M3 (0.375+/-0.020 Msun) and M7 (0.098+/-0.005 Msun)
components. The lens is unusually close, at 0.998+/-0.047 kpc, compared with
the majority of microlensing events, and despite its intrinsically low
luminosity, it is likely that AO observations in the near future will be able
to provide an independent confirmation of the lens masses.
