Abstract

The first Long Duration Event (LDE) observed with Hinode EIS using a high spectral resolution raster scan is described. The hot plasma features include a cusp-shaped arcade associated with a thermal RHESSI source, cooling post-flare loops, complex plasma flows and an EIT observation that shows expanding loops and inflows characteristic of the standard magnetic reconnection model for solar flares. A Coronal Mass Ejection (CME) is also seen by LASCO. The cusp is well observed in the Ca XVII line and we find enhanced line broadening above this region. Doppler velocity observations for the post-flare loops show both up-flows and clown-flows that are interpreted as due to siphon flows.
