AB: We present analysis of microflares (small active region associated flares below GOES C class) using RHESSI and Hinode/XRT. RHESSI has observed well over 1,000 microflares since Hinode launched late in 2006 and of these over 150 have good Hinode/XRT coverage. We use RHESSI to obtain the temperature, emission measure and non-thermal power-law parameters from spectral fitting. We compare RHESSI and Hinode/XRT images to locate the thermal and non-thermal emissions. Taking advantage of the sensitive high-resolution capability of XRT for the softer X-rays, we investigate the resulting heating and evaporation from the accelerated electrons observed via the non-thermal emission by RHESSI.
