Paper Abstract

Variability in the solar UV and EUV irradiance is an important driver of the temperature of the Earth's upper atmosphere. The variation of the Magnesium II emission at 280 nm is a useful proxy for the variation at shorter wavelengths. Currently, the emission by the Mg II lines is measured only a few times per day at best, and often only a single measurement per day is available. An instrument dedicated to measuring only the Magnesium II solar output on a high time cadence will greatly improve our knowledge of the energy input to the atmosphere. Such an instrument would have very modest power, size, and weight requirements, and could easily be one component of a suite of solar instruments on a future space mission. We present some design options for a lightweight solar Magnesium II monitor that would provide measurements suitable for space weather studies.
