| Abstract: |
The Hinode EUV Imaging Spectrometer (EIS) observed a long duration flare with a weak impulsive phase that appears to conform to the standard two-ribbon flare reconnection model. EIS scanned the flare site during the impulsive phase and observed Fe XXIII and Fe XXIV line emission that closely followed the flare hard X-ray emission while the line profiles showed significant non-thermal broadening. We suggest that a shock originating at the reconnection site which sweeps up and heats the coronal plasma can account for our observations. |
