Swift discovered GRB050713a and slewed to begin observing with its narrow field instruments only 72.6 seconds after the burst onset, while the prompt gamma-ray emission was still detectable in the BAT. Simultaneous emission from two flares is detected in the BAT and XRT. This burst marks just the second time that the BAT and XRT have collected simultaneous data on a burst and it marks the first time that both instruments have produced a well sampled, simultaneous dataset covering multiple flares in the prompt emission. In addition to the Swift instrumentation coverage of GRB050713a, we report on the Konus-Wind detection of the prompt burst emission in the energy range 18-1150 keV, an upper limiting GeV measurement of the prompt emission made by the MAGIC atmospheric imaging Cherenkov telescope and XMM-Newton observations of the burst afterglow. Periods of simultaneous observation between Swift XRT and XMM-Newton produce consistent results. Together, these four observatories provide unusually broad high energy spectral coverage of the prompt emission and detailed x-ray follow-up of the afterglow for two weeks after the burst trigger.
