The air imaging Cherenkov telescope MAGIC observed GRB050713a and GRB050904 during their prompt emission phase. The measurements were triggered by the SWIFT satellite. The MAGIC telescope started the observation 40 and 92 seconds respectively after the burst onset, while the gamma-emission in the keV range was still active. The observations followed up in the GRB afterglow phase. Due to its low energy threshold, large effective area, and, in particular, its capability for fast slewing, the MAGIC telescope is best suited for the detection of the prompt emission of GRBs in the GeV energy range. Results will be presented.
