Introduction: Prominences are well suited for investigating the energy balance, radiative transfer, and complex interchange of mass between the solar photosphere, chromosphere and corona. They are still a subject of interest in solar physics. The spectral analysis and morphological properties of prominences usually provide us with an important information on the dynamics, radiative transfer, and stability of the prominences. Of a great interest are the prominences with centrál reversal in their Hα profile since they may display appreciable variations in activity. Such observations have also been included in our scientific programme with the Stará Lesná spectrograph because a long series of Hα profiles of prominences can be recorded.
