    amplitude (practically to complete disappearance of
    Blazhko effect); Pi = 40.8d. Variations of Max light
    phase up to 0.14P; magnitude in Max var in the range
    up to 0.6m, that in Min var in the range up to 0.1m
    [03418].According to [07270], a cycle ~4 yr is present
    in Blazhko effect amplitude changes; at the end of
    the cycle the Blazhko effect phase changes abruptly
    by 0.25Pi. Magnetic field strength varies with the
    pulsational period [09339].
