Abstract

Data on continuum variability of the Seyfert galaxy NGC 4151 nucleus are compiled. The most of them related to new cycle of the nucleus activity in 1989-1996. X-ray through the UV and optical data show remarkable similarity in variability characteristics to those of blazars and do not contradict the supposition that new cycle of activity mainly caused by synchrotron jet.
