Time evolution of the X-ray and radio emission associated with the electron event on 2011 Mar 24. From bottom to top: time profiles of the GOES soft X-ray flux, of the RHESSI 25–50 keV count rates (corrected for instrumental effects), and of the radio flux at microwave frequencies, and dynamic spectra in the meter-wave and decameter-hectometer-wave radio range. The interval used for the computation of the RHESSI spectrum shown in Fig. 3 is indicated by the pair of red lines in the two bottom panels.
