Remark: Porb = 0.13755d. Usually near maximum brightness, occasional deep fadings. Numerous photometric periods were reported. According to [N0138], the star experiences alternating "negative superhump" (P = 0.13270 - 0.1398d) and "positive superhump" (P = 0.14840 - 0.14926d) intervals, with amplitudes of several tenths of a magnitude. Quasiperiodic oscilations, flickering.
