FASR Science IDENTIFICATION OF EMISSION MECHANISMS! Nature & Evolution of Coronal Magnetic Fields        Measurement of coronal magnetic fields – higher cadence – higher spec resln; preflare build-up and release; signature of preflare state; nature of trigger mechanisms        Temporal & spatial evolution of fields        Role of electric currents in corona        MHD/other  oscillations & QPOs – “coronal seismology” Coronal Mass Ejections        Birth & acceleration; shock formation; coronal cavity? Magnetic connectivity/toplogy & dynamics        B, nrl, nth, T,  magnetic flux??        Prominence eruptions        Relation to SEPs & other SW predictors        Chromo/coronal waves Flares  solar/stellar connection/analogies        Energy release – dm burst em mech/instability identification        Plasma heating – microphysics of energy release        Electron acceleration and transport – CME/dm connections?        Origin of SEPs

FASR Science (cont) The “thermal” solar atmosphere    coronal holes and streamers (low freq); fast CH evolution        Coronal heating - nanoflares        Thermodynamic structure of chromosphere in AR, QS, CH        Formation & structure of filaments/prominences        Transition between thermal/nonthermal AR        Oscillations/response of convec zone        Scudder Origin of Solar Wind??        Birth in network – nanoflares?        Tomography of inner heliosphere (if low-freq)        Turbulence & waves in inner helio (if low-freq)        Magnetic field constraints (… maybe – hard) Space weather, LWS, and synoptic studies

FASR Science (cont) As a comprehensive, dedicated solar instrument sensitive to magnetic fields, eruptive phenomena, their locations, and physical properties – and capable of  providing many of these in real time or near-real time - FASR is an excellent LWS/Space Weather instrument. As a stable, well-calibrated instrument FASR will make important contributions to synoptic studies: long term monitoring of magnetic, thermal, and irradiance properties of the Sun.
