Abstract
Juno has been inserted in the Jupiter orbit on July 4. JIRAM [1], the Jovian InfraRed Auroral Mapper on board the spacecraft, is equipped with an infrared camera and a spectrometer working in the spectral range 2-5 µm. The instrument was primarily designed to give a contribution to the study of Jupiter's magnetosphere and its interaction with the planet, in particular by studying the infrared aurora. JIRAM will also be used to investigate on some properties of the atmosphere through the thermal emission of the planet detection. In particular, JIRAM is able to measure the concentrations of atmospheric compounds that are significant in atmospheric chemistry and the formation of clouds like H2O, NH3 and PH3 by observing in the Jupiter Hot Spots. Secondary JIRAM objectives are the study of Jupiter's clouds and, to some extent, the dynamics of the atmosphere. We present a survey of the observations that JIRAM has performed during the first passage near the planet at the end of August 2016. [1] Adriani A. et al., JIRAM, the Jovian Infrared Auroral Mapper.
