EOVSA SOLAR RADIO BURST ANALYSIS IN SUPPORT OF RHESSI

THIS PROJECT PROPOSES TO COMPLEMENT RHESSI DATA ON NONTHERMAL ELECTRONS ACCELERATED IN SOLAR FLARES WITH THE DATA AND DATA PRODUCTS OBTAINED WITH MICROWAVE IMAGING SPECTROSCOPY AVAILABLE FROM EXPANDED OWENS VALLEY SOLAR ARRAY (EOVSA) IN THE SPECTRAL RANGE FROM 2.5 18 GHZ. WE MAKE THE CASE THAT THE EOVSA AND RHESSI DATA ARE PERFECTLY COMPLEMENTARY TO EACH OTHER. FORWARD FIT OF THE EOVSA SPATIALLY RESOLVED SPECTRA WILL BRING THE MUCH-NEEDED INFORMATION ABOUT MAGNETIC FIELD IN THE FLARING LOOPS AND ITS EVOLUTION DURING THE COURSE OF THE FLARE. EOVSA DATA WILL ALSO BRING ADDITIONAL CONSTRAINTS ON THE NONTHERMAL ELECTRON DISTRIBUTIONS ESPECIALLY AT THE HIGHENERGY RANGE OF A FEW HUNDRED KEV TO A FEW MEV. WE PROPOSE TO ANALYZE IN DETAIL A FEW EVENTS (BOTH ON-DISK AND LIMB FLARES) JOINTLY OBSERVED BY EOVSA AND RHESSI AND TO INVESTIGATE THE PROCESS OF MAGNETIC ENERGY TRANSFORMATION TO THE NONTHERMAL AND THERMAL ENERGIES DURING SOLAR FLARES. THE MULTI-WAVELENGTH DATA ANALYSIS PROGRAM AS PROPOSED HERE IS EXPLICITLY AND HIGHLY RELEVANT TO THE FIRST GOAL OF THE HELIOPHYSICS DECADAL SURVEY DETERMINE THE ORIGINS OF THE SUN S ACTIVITY AND PREDICT THE VARIATIONS IN THE SPACE ENVIRONMENT AND TO THE FOURTH DECADAL SURVEY GOAL DISCOVER AND CHARACTERIZE FUNDAMENTAL PROCESSES THAT OCCUR BOTH WITHIN THE HELIOSPHERE AND THROUGHOUT THE UNIVERSE.
