文摘

The light curves of CZ Aql, BO Cet, V380 Oph and EF Tuc are dominated by strong flickering. The absence of flickering in Lib 3 permits to exclude the star from the list of CV candidates. Orbital variations are observed in BO Cet and V380 Oph but not in CZ Aql and EF Tuc. CZ Aql may exhibit superhump-like variations. Circumstantial evidence points at a possible magnetic nature of CZ Aql.
