JunoCam at PJ60

PJ60 (on 2024 April 9) began with a medium-range flyby of Io, which revealed more volcanic activity than JunoCam has hitherto seen, including four active plumes on the limb, and a spectacular new red ring around a far-southerly caldera.  Moving on to Jupiter, JunoCam produced a complete map of the planet, at a time when the planet had almost ceased to be visible to ground-based observers.  Although north polar images were again impaired by Jupiter’s radiation belt, four circumpolar cyclones were fully imaged.

UPDATE, 2024 June 20:   We have now made map projections of the Io images, and in a supplemental report these are assembled into preliminary global maps, for PJ60 and for all of Juno’s recent flybys.  Thus we present the most complete JunoCam map of Io, and show the dramatic effects of the huge eruption of the Nusku volcano, which occurred between PJ58 and PJ60.   This report is here:
