We point out that the corresponding inverse-Compton flare at TeV--PeV region is more enhanced than synchrotron by a Lorentz factor square \Gamma^2, which is already excluding \Gamma 200 and will be detected by future TeV - PeV observatories, CTA, Tibet AS + MD and LHAASO for \Gamma 30. We also show that PeV photons emitted from the Crab Nebula are absorbed by Cosmic Microwave Background radiation through electron-positron pair creation.
