英文摘要: This paper reports the obtained analysis data on the spatio-temporal evolution of sources of microwave and hard X-ray pulsations for the SOL2011-06-07T06:16 event based on the observation data of the RHESSI spectrometer and the Nobeyama radioheliograph. The position of the considered pulsation sources changes from one pulsation to another. The motion of the X-ray sources is predominantly longitudinal in nature in relation to the inversion line of the magnetic polarity. The obtained analysis data on the evolution of X-ray sources are in good agreement with the results of the radio image analysis. The radio brightness center at 34 GHz changes its position from one pulsation to another along the inversion line of the magnetic polarity throughout the burst. According to the AIA/SDO telescope data, the flare region images in the ultraviolet range demonstrate a well-defined eruption of the magnetic flux rope. The flare energy release can likely be triggered by the erupting magnetic flux rope; the successive interaction of different parts of it with different loops of the surrounding magnetic arcade can result in their successive "ignition" and, as a consequence, lead to the observed changes in the position of X-ray and microwave sources from one pulsation to another.
