| Abstract | SolACES (SOLAR Auto-Calibrating EUV/UV Spectrophotometers) was designed to monitor (quasi) continuously the Extreme UV (EUV) and UV radiation of the Sun in the wavelength range between 16 and 220 nm on-board the International Space Station (ISS). A novel feature of the instrument is its capability to auto-calibrate the instrument repeatedly during the whole mission via absolute flux detection inside two ionization chambers. SolACES is part of the SOLAR space science instrument package which was mounted into a Coarse Pointing Device (CPD) on the External Payload Facility of the ESA Columbus module. The CPD compensates for the ISS orbital orientation changes, and points SolACES to the Sun together with another solar science payload: the Solar Spectrum measurement instrument or SOLSPEC. This enables simultaneous and complementary measurements of the two instruments for the spectral irradiance between 16 nm and 3 μm. |

| Mission Description | The SOLAR monitoring observatory (SOLAR) was an ESA science observatory mounted externally on the Columbus Laboratory, a module of the International Space Station. The primary goal of SOLAR is the (quasi-) continuous measurement of the solar "constant" in order to separate solar effects from human influence on climatology (in progress). SOLAR was launched on February 2008 aboard STS-122. It was originally composed of three scientific instruments: SOVIM (Solar Variability and Irradiance Monitor), SOLSPEC (Solar Spectral Irradiance Measurements), and SolACES. SOLSPEC and SolACES provided detailed measurements of the Sun's spectral irradiance from April 2008 to mid-February 2017 from 16 nm to 3 microns.
