1 Otero, Sebastian Alberto Non-magnetic CV.
2 GCVS Team SB (P = 0.13854d [R.P.Kraft, ApJ 134, 457, 1964.]). Outside the outburst there are variations of light (eclipses) with Delta(m) = 0.30m, Min I = 2444401.399 + 0.1377d*E (D ~0.2P). The shape of the light curve and the depth of minima differ from cycle to cycle. The brightness in minima shows fluctuations apparently connected with the presence of a hot spot [H.Drechsel, J.Rahe, A.Holm, J.Krautter, AsAp 99, N1, 166, 1981.].
