In this work we obtain the temperature (T) and emission measure (EM) for solar X-ray emission, using RHESSI and GOES data, at times for which there are no solar flares. Approximately 8700 time intervals during the RHESSI mission, from launch until August 2006, are analyzed. We find that high temperature emission, in the temperature range of 5 to 10 MK, is typically present during active times. When comparing temperature measurements, we find that RHESSI temperature measurements are consistently higher than GOES measurements, with smaller emission measure for RHESSI, but with values for the two instruments that are not necessarily well correlated.
