UV spectroscopy with SOHO Original Research Article

The UV spectroscopy from SOHO has provided new and exciting results from a wide range of phenomena observed on the Sun. Determination of plasma parameters such as velocity, density, temperatures, line widths and abundances have provided new physical insight into fundamental problems in solar physics. These include magnetic reconnection, quiet Sun coronal heating, active region dynamics, flows in solar flares, formation of the solar wind, determination of coronal mass ejection onset, characteristics of coronal waves and the twisting of magnetic structures. This paper will review these results and discuss what can be achieved with future spectroscopic instrumentation.
