[en] The Juno mission, orbiting Jupiter since July 2016, offers an unprecedented opportunity to study Jupiter, from its internal structure to its magnetospheric environment. Juno-UVS is a ultraviolet (UV) photon counting spectrograph with a bandpass of 68<λ<210 nm. The main purpose of Juno-UVS is to observe and characterize Jupiter’s UV auroral emissions and provide global context for Juno’s in-situ particles and fields instruments. Juno is a spinning spacecraft that nominally spins at 2 rpm, so it spends a significant amount of time observing the sky background, including stars, interplanetary medium and extragalactic sources. We present here how we use this information to: (i) characterize and calibrate Juno-UVS; and (ii) monitor the detector response over the mission.
