Description
During two years since the beginning of operation, the MAGIC telescope could observe several GRB events in the prompt and early afterglow phase. Thanks to its innovative design, the telescope could promptly react to incoming GCN alerts, rapidly slew to the burst coordinates within on average 45 seconds, performing observations with an energy threshold spanning from 80 to 200 GeV. The observations did not reveal any γ-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.
