| Abstract: | An optical monitoring shows Blazar object S5 0716+714 has complex Intra-Day Variability (IDV) behaviour. In this paper, we introduce a method of non-linear time series analysis, and calculate the correlation dimension of the IDV light curves of S5 0716+714 over seven nights in the December of 2006. According to our calculations, the correlation dimension D ≈ 1.993 ? 5.178 for all of the observed data, it is implied that the IDV behaviour may be a chaotic system with some additional noise. |
