AB: The Magnesium II h \& k doublet at 280 nm is an important diagnostic of solar activity. The Solar-Stellar Irradiance Comparison Experiment (SOLSTICE) onboard the Solar Radiation and Climate Experiment (SORCE) measures the solar spectral irradiance in the neighborhood of Mg II nearly every orbit. The SOLSTICE instrument on SORCE has a resolving power of 3000 in the MUV,which is sufficient to resolve the emission cores in the Mg II lines. These observations allow analysis of Mg II variation on timescales from hours to years as the SORCE data record grows. We will discuss comparisons of the Mg II index derived from SORCE SOLSTICE with lower-resolution instruments.
