Solar Prominences Observed by Soho (SUMER, CDS, EIT) and Ground-Based Observatories (GBO)

Abstract

We present two sets of prominence observations in higher lines of the hydrogen Lyman series (from Lδ to L-9), together with some other UV lines. These data have been obtained by the Solar Ultraviolet Measurements of Emitted Radiation (SUMER) onboard the SOHO satellite in June 1997. Coordinated observations were also taken by other SOHO instruments: Coronal Diagnostic Spectrometer (CDS) and Extreme-Ultraviolet Imaging Telescope(EIT) and with the coronagraph of the Wroclaw University Observatory at Bialkóv, the spectrograph of the Ondřejov Observatory. We demonstrate the basic characteristics of the calibrated line profiles and compare them with the theoretical profiles computed from isothermal-isobaric models
