Abstract
The Compact SOLSTICE, a compact far and mid ultraviolet (FUV and MUV) spectrograph,
flew on a sounding rocket on 18 June 2018 to validate and potentially calibrate the SOLar
STellar Irradiance Comparison Experiment (SOLSTICE) onboard the Solar Radiation Climate Experiment (SORCE) spacecraft. This article reports the instrument design, the calibration of the FUV channel, and the FUV irradiance measurements. Irradiance measurements are compared to SOLSTICE showing agreement within the combined instrumental uncertainties at most wavelengths, including the H Lyman-α emission at 121.6 nm. Some unexplained differences in line ratios between 130.5 nm and 147.5 nm are observed.
