Abstract:

Gamma Ray Burst and Soft Gamma Repeaters are neither standard candle nor isotropic explosions. Our model explains them as strong blazing of a light-house, spinning and precessing gamma jet. Such jets at maximal output (as GRBs in Supernova like sources at cosmic edges) or at late lower power stages (SGRs in nearer planetary nebulae in galactic halo) may blaze the observer by extreme beaming $(\Omega < 10^{-8} )$ and apparent huge luminosity.

Key words: GRB, Jet, Inverse Compton, SGR
