1 Otero, Sebastian Alberto Dwarf nova outbursts (V= 14.2 - 17.4). Variations between 14.3p and 18.3p were already mentioned in 1942AnHar.109...11B.
2 GCVS Team After 1932 variations 14.3m - 18.3m were noted; according to [E.H.Boyce, HA 109, N2, 1942.], P = 275d. Observations in 1961 - 1964 did not confirm P = 275d, fluctuations of light with a period of several minutes were suspected [T.D.Kinman, C.A.Wirtanen, K.A.Janes, ApJ Suppl 11, N100, 1965.]. The spectral data are for 1981.
