We present results of multitemperature analysis of GOES C7.2 class flare observed on 2003 March 29. This event occurred close to the centre of the solar disk (S12W14) at 10:11 UT and had two maxima in X-rays. We have performed analysis of physical parameters characterizing evolution of conditions in the flaring plasma. The temperature diagnostics have been carried out using the differential emission measure (DEM) approach based on the soft X-ray spectra collected by RESIK Bragg spectrometer. Analysis of data obtained by RHESSI provided opportunity for a detailed analysis of HXR emission with good energy and spatial resolutions.
