The Solar EUV Research Telescope and Spectrograph is a rocket-based instrument that uses high resolution extreme ultraviolet spectra to investigate features in the solar corona and transition region. The 1999 flight occurred on 24 June 1999 and obtained spectra from both active regions and quiet sun regions on the solar disk covering a spectral bandpass 300-355 angstroms We report here the calibrated intensities and measured linewidths determined from the spatially-averaged spectra of both active regions and quiet sun regions respectively. In addition, we determine a distribution of non-thermal velocity components from the measured linewidths of the identified lines. This distribution provides a quantitative constraint on the available energy of non-thermal origin in the observed regions which is available for coronal heating.
