Remarks

1 Otero, Sebastian Alberto Period decrease (4.4 s in about 100 yr).
2 Otero, Sebastian Alberto V Sge star.
3 Otero, Sebastian Alberto ASAS-3 data confirm the presence of outbursts. Supersoft X-ray source; CV with stationary hydrogen burning on the white dwarf.
4 GCVS Team B-V ~ +0.45, U-B ~ -0.72. Proposed as an optical counterpart of the transient X-ray source Cen X-2 [O.J.Eggen, K.C.Freeman, A.Sandage, ApJ 154, L27, 1968.], though no optical bursts were observed.
