A Study of the Periodicity of the Light Curve of STHZthe BL Lac Object ON 231
In this paper, we collect the data of ~100 years in the B-band of the BL Lac object ON 231 and use these to analyze the periodicity of the optical light curve. We apply two different methods,Jurkevich's test and the wavelet analysis method.Both methods reveal the existence of periods of 13.6±1.5 and 26.1 years in the light curve.
