AbstractWe report the discovery of year-scale X-ray variation in the nuclear region of the M87 by reanalyze the eightChandraobservations from 2007 to 2008. The X-ray spectra are fitted and decomposed into disk and flaring components. This year-scale X-ray variability can be explained quite well by a simple clumpy accretion model. We conclude that the central super-massive black hole of M87 was accreting a cloud of similar to 0.5 M-circle dot at that time.
