Abstract
The three instruments on the Hinode satellite give a wealth of information about the aftermath of reconnection in solar flares. As magnetic fields reconnect during solar flares, flows and heating are observed in the corona as well as in the chromosphere, where the magnetic fields are line tied. The X-Ray Telescope and the Extreme ultraviolet Imaging Spectrometer (EIS) have the temperature sensitivity and spatial resolution to observe these phenomena in the corona, and the Solar Optical Telescope and EIS can observe the signatures of heating and flows, respectively, at the flare footpoints. In this chapter, we will review the observational evidence for heating and flows in the corona and chromosphere in the aftermath of flare reconnection.
