"The MAGIC Cherenkov telescope in La Palma has observed GRB050713A 40s after T0.

Abstract
"The MAGIC Cherenkov telescope in La Palma has observed GRB050713A 40s after T0.

The first look at the MAGIC data did not reveal strong gamma ray emission above 175GeV. The flux limit derived at very high energies by MAGIC is 2-3 orders of magnitude lower than the extrapolation from the X band [1]. A detailed analysis is in progress.
