The question of variability of Crab nebula’s radiation in two energy ranges, x-ray (range 2–10 KeV) and very high energy gamma-radiating (range > 1 TeV), has been considered. The presence of sinusoidal quasiperiodic variations of x-ray radiating with period a P = 862 d. is shown. Positive correlation of temporary variations, in x-ray and gamma-radiating (HEGRA’s data) has been received.
