AB: A model of solar spectral irradiance has been developed that predicts the solar spectrum near Mg II at 280nm. This model uses sun spot, active region, and quiet sun spectra and high resolution limb darkening curves observed by the Naval Research Laboratory's HRTS rocket as the basis for modeling solar spectral variability. Ground-based Ca II K images are used to determine the contribution of each of these solar surface features to the total solar spectrum. The resulting spectra are at a resolution of about 0.01nm. These model spectra are currently being compared to observed spectra in order to identifty the solar sources of spectral variability. A predicted Mg II index is compared with the observed values of the index.
