1 Otero, Sebastian Alberto The two components of the binary are CTTS stars. On JD 2456975.56 RW Aur A was found to be at a deep minimum with V= 13.80; B-V= 0.70 while RW Aur B was recorded bright at V= 12.92 and B-V= 1.34.
2 GCVS Team VB A (B 12.5m, dM0e, 1.2", 254deg). The companion probably flares with an amplitude 0.5m - 0.7m [W.Fuertig, W.Wenzel, MVS 2, H.1, 11, 1963., N.M.Shakhovskoj, Tadj. Byull. N43-44, 3, 1966.]. Possible period of axial rotation is 100d [I.M.Ishchenko, Perem. Zvezdy 18, 293, 1971.]. OH emission.
