      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.
