TO COMPUTE THE LORENTZ FORCE DENSITY WE PROPOSE TO RETRIEVE THE VARIATION IN HEIGHT (AS WELL AS LATERAL SPACE) OF THE MAGNETIC FIELD VECTOR THROUGH THE USE OF ESTABLISHED INVERSION CODES APPLIED TO HIGH SPECTRAL RESOLUTION POLARIMETRIC DATA ACQUIRED BY THE HINODE/SOT SPECTROPOLARIMETER. BY RETRIEVING THE HEIGHT VARIATION OF THE MAGNETIC FIELD IT WILL BE POSSIBLE TO DETERMINE THE FULL CURRENT DENSITY AND THUS GENERATE MAPS OF THE LORENTZ FORCE DENSITY ITSELF WITHOUT MAKING ASSUMPTIONS ABOUT THE BEHAVIOR OF THE MAGNETIC FIELD. WE WILL EMPLOY THE NICOLE INVERSION CODE BUT DEVELOP IMPROVED IMPLEMENTATION STRATEGIES WITH THE GOAL OF MORE ROUTINE PRODUCTION OF HEIGHT DEPENDENT INVERSION PRODUCTS. THE ACTIVE REGION TARGETS FOR THIS PROJECT HAVE HINODE/SP SCANS TAKEN BEFORE AND AFTER A SELECTION OF MAJOR FLARES THAT VARY IN THEIR FLARE-RELATED ACOUSTIC ACTIVITY. THE PRIMARY EMPHASIS OF THE PROPOSED INVESTIGATION IS A NOVEL ANALYSIS OF DATA FROM THE HINODE MISSION SUPPLEMENTED BY ANALYSIS OF DATA FROM SDO WHICH ARE BOTH CURRENTLY-OPERATING MISSIONS OF THE HELIOPHYSICS SYSTEM OBSERVATORY (HSO). THE ANTICIPATED RESULTS WOULD ADDRESS THE FIRST AND FOURTH HIGH LEVEL SCIENCE GOALS FROM THE HELIOPHYSICS DECADAL SURVEY NAMELY TO "DETERMINE THE ORIGINS OF THE SUN S ACTIVITY AND PREDICT THE VARIATIONS IN THE SPACE ENVIRONMENT" AND TO "DISCOVER AND CHARACTERIZE FUNDAMENTAL PROCESSES THAT OCCUR BOTH WITHIN THE HELIOSPHERE AND THROUGHOUT THE UNIVERSE." THE PROPOSED INVESTIGATION WILL CHARACTERIZE FUNDAMENTAL PROCESSES OCCURRING AT THE PHOTOSPHERE DURING A FLARE POTENTIALLY LEADING TO INSIGHT INTO ONE MANIFESTATION OF THE SUN'S ACTIVITY. INSOFAR AS FLARES ALSO OCCUR ON OTHER STARS IT MAY CHARACTERIZE A PROCESS OCCURRING THROUGHOUT THE UNIVERSE.
