Scientific paper

Our understanding of the emission of the solar corona between about 25 and 170 Å is still incomplete. Only a limited amount of observational data exist, and analyses of those data show that up to half of the lines have not been assigned. Here we report on our effort to produce a complete set of spectral lines based on existing spectral modeling data, laboratory measurements, and new calculations. New line lists have been produced for the emission of neon and magnesium in this wavelength band. We compare spectral data from the Livermore electron beam ion trap and the Flexible Atomic Code with various solar EUV spectra, such as those obtained from the Atmosphere Explorer-E satellite and Aerobee Rocket observations. This work was supported by NASA's Solar and Heliospheric Physics Program award NNX07AH98G. Work at LLNL was performed under the auspices of the U.S. DOE under Contract DE-AC52-07NA27344.
