SOLAR on Station

SOLAR installed on ESA’s Columbus laboratory on the International Space Station. SOLAR consists of three complementary instruments: SOVIM (SOlar Variable and Irradiance Monitor) covers the near-ultraviolet, visible and thermal-infrared regions of the spectrum; SOL-ACES (SOLar Auto-Calibrating Extreme UV/UV Spectrophotometers) measures the extreme ultraviolet; and SOLSPEC (SOLar SPECtral Irradiance measurements) covers the 180–3000 nm wavelength range.
