  During its cycle-1 observation period, between April 2005 and March 2006, the
MAGIC telescope was able to observe nine Gamma Ray Burst (GRB) events since
their early beginning. Other observations were performed during the following
months in the cycle-2 observation period. The observations, with an energy
threshold spanning from 80 to 200 GeV, did not reveal any gamma ray emission.
The computed upper limits are compatible with a power law extrapolation, where
intrinsic fluxes are evaluated taking into account the attenuation due to the
scattering in the metagalactic radiation field.
