Cycle 23 flare temperatures and emission measures as derived from GOES X-ray data

Solar X-ray observations recorded by the series of geostationary observational environmental satellites (GOES) are analyzed over a time interval of the 23rd solar cycle. Statistical analysis of a large database of GOES events is performed. Temperature and emission measures derived based on GOES fluxes for all events are compared and analyzed. A specific application of GOES X-ray measurements to space weather forecasting is discussed. Namely, using an information about maximum temperature and maximum emission measure of a given flare one can assign a probability to this flare of being “non-SEP associated”.
