	1) Signatures of solitary waves in coronal holes

        Sequence: 99.02.27_marco
 
        SCI_SPEC: Detection of solitary waves in coronal hole plume
                  and interplume region, by monitoring of density
                  fluctuations using visible polarized brightness.
                  UV measurements of line intensity and profile of
                  Lya provide averaged plasma parameters of
                  the studied region.
