The ovals are observed at stationary positions in 2.57 micron radiance maps derived from JIRAM's spectrometer channel data acquired on Aug 2th 2016 (observation phase #2) and Aug 25th 2016 (#3) during Juno's first perijove passage. A quantitative analysis of these three features is performed by means of an inversion technique based on Bayesian method.ELETTRONICOenConference abstracthttps://www.epsc2017.eu/information/general_information.html2017EPSC...11..773FFIS/05 - ASTRONOMIA E ASTROFISICA
