UV SPECTRAL-LINES FROM CORONAL TRANSIENTS

We investigated the UV emission expected from solar coronal transients , selecting some spectral lines which will be observed with the UVCS s pectrocoronagraph onboard the SOHO spacecraft. The line intensities we re calculated starting from a representative, simplified model of coro nal transient. We discuss how the considerd intensities depend on the physical parameters of the examined structures. This work is aimed to give a contribution in defining and preparing the future observations of coronal transients and coronal mass ejections by the UVCS/SOHO.
