Title : Magnetic field configuration of the active region corona and energy release during solar flares 

Abstract : Solar eruptive phenomena occur at different spatial, temporal and energy scales. A flare is the most violent form of solar activity which essentially represents sudden release of excess energy stored in the magnetic fields of solar corona. The contemporary multi-wavelength observations have immensely improved our understanding of the various physical processes occurring in different atmospheric layers of the Sun during a solar flare. The standard flare model has been successful in broadly recognizing these physical processes as the consequence of large-scale magnetic reconnection in the corona. Jets and coronal mass ejections are among important phenomena associated with solar flares.
The objective of the present talk is to summarize the multi-wavelength observations of solar flares and associated phenomena taken mainly from the space borne instruments over the last decade. I will highlight some recent works on magnetic field modelling of the active region corona that shed light upon triggering and energy release mechanisms. I will further discuss contemporary observations on flare-flux rope-CME associations along with the interplanetary consequences of the solar eruptions.
