1 Otero, Sebastian Alberto Microquasar. J-K= 1.1; B-V= 1.4. Quiescent state V= 17.8 - 18.3. 1983ApJ...266L..27M.
2 Otero, Sebastian Alberto VSP Note: 20.8 Vmag. star 6" to the NNE.
3 GCVS Team Novalike outbursts were observed in 1917 (Max JD2421540) and in 1975 (Max JD2442646). In quiescent state probably ellipsoidal light variation is observed with P = 0.325d and A = 0.2m [J.E.McClintock, L.D.Petro, R.A. Remillard, G.R.Ricker, ApJ 266, L 27, 1983.], and also slower light variations with P = 7.39d [H.Tsunemi, M.Matsuoka, K.Takagishi, ApJ 211, L 15, 1977.] or 7.8d [T.Matilsky, H.V.Bradt, J.Buff, G.W.Clark, J.G.Jernigan, P.C.Joss, B.Laufer, J.McClintock, D.Zubrod, ApJ 210, L 127, 1976.].
