27. June 10, 2009 Chamberlin - Solar Flares - REU 2009 27 Conclusions Multiple images and spectral measurements are key to understanding energetic of flares
New measurements (Hinode, Stereo, EVE, AIA, etc.) will lead to a much greater understanding of these processes
Biggest mystery still is the ‘trigger’
Another topic to that is not fully understood is the relationship of CMEs and Flares
