摘要：

The statistical characteristics of the optical variability of the quasar 3C 446 are examined, using new observations covering the 1988 burst, in order to solve the apparent contradictions among several recent analyses. Following two different approaches, power spectrum and structure function analyses, it is confirmed that the variability of 3C 446 exhibits a periodic component with period of about 1540 days. It is also shown that the nonstationarity of the processes describing the time behavior of 3C 446 can explain some of the features observed in its power spectrum.
