SUMER EUV spectral atlas in the range 800 - 1500 Angstroem shown in first order converted to physical units using ground and onboard calibration data. The SUMER spectrum with all its details clearly demonstrates the strength of this instrument. The solar spectrum below 1200 A is not very well known. Thus, the present spectral atlas, and SUMER observations in general, represents a new important diagnostic tool to study essential physical parameters of the solar atmosphere. It includes emission from atoms and ions in the temperature range 10,000 to 2,000,000 K. Thus, emission lines and continua emitted from the lower chromosphere to the lower corona can be studied.
