SOLSTICE II -- Magnesium II Index
Abstract
The Magnesium II core-to-wing index is a critical proxy for solar chromospheric variability. The SOLar-STellar Irradiance Comparison Experiment (SOLSTICE) has been making this measurement since launch in 2003. Recent analysis comparing the primary channel measurement to the backup channel has indicated that an instrument artifact was introduced in early 2006. This poster will describe the magnitude of the artifact and present the corrected time series. We will compare the corrected dataset to the other Mg II data records over the past ten years.
