AbstractA Fourier series fitting of order 10 to the historical light curve of OJ287 (3648 data points) is presented with correlation coefficient similar to 0.73. It is found that the Weierstrass function may be used to imitate the short time scale variability of OJ287. A fractal curve constructed by the function possesses the similar correlation coefficient to the light curve as the regression curve. We also calculate the capacity-dimension, information-dimension and correlation-dimension of the light curve. The calculations indicate that their values > 1.
