The solar spectrum in the SUMER wavelength range is rich in emission lines. The analysis of this near-limb quiet-Sun spectrum revealed spectral details in the range from 660 Å to 1175 Å and resulted in a line list, including very faint lines. Only few lines remained unidentified. Other spectra from different regions of the Sun have to be analysed to find out commonality and variability of spectral features of the Sun.

The SUMER project is financially supported by DARA, CNES, NASA and PRODEX (Swiss contribution). Additional financial support is being provided by the participating institutions along with general administrative assistance at various phases of the project. The instrument development and/or commissioning has been carried out by a large dedicated team of engineers, scientists, and technicians co-ordinated by a management support group, and scientific advice was provided by a large group of Associate Scientists.
The authors greatly acknowledge their contributions. We particularly appreciate the efforts of the SUMER operations team.
Table 1: Line List -
This list of spectral lines in the
wavelength range including some 2nd order lines below 590 Å
was compiled from a spectrum which was recorded with detector B
on the solar disk near the north limb.
It was generated from a number of sections recorded on the KBr photocathode
each about 20 Å wide, and complemented by bare photocathode lines at the
lower wavelength limit
