Jupiter in 2015/16:  Final report

John Rogers (British Astronomical Association) & Gianluigi Adamoli (JUPOS team),

In the 2015/16 apparition, activity on the planet developed more-or-less in line with predictions we made a year earlier, albeit more slowly than expected.  Thus a sector of the NEB expanded northwards (although this event then regressed); normal activity continued in the SEB (though with a brief pause); oval BA decelerated as adjacent turbulence declined; and a North Temperate Disturbance continued to dominate that domain. Both the NTB and STB were largely absent.

            These major developments during the apparition have already been covered in our interim reports.  This report adds tables of the locations and speeds of the major spots and the major currents. Otherwise, this report concentrates on fine details, which are still giving us new insights into the dynamics of the jovian atmosphere.  For example, we report circulation patterns developing in the STZ, and waves moving along the SEBs and S4 jets. As usual, we detect both anticyclonic ovals and retrograding or slow-moving dark spots in most of the high-latitude domains, and prograding spots on the N2, S2 and S3 jets.  For a shorter summary of the apparition, with more background information, we recommend Report no.9 [ref.1].

            Three Appendices present topics of special interest:

Appendix 1:  The SEBs jet in 2016: wave motions and super-fast motions.

Appendix 2:  Mapping the circulation within the GRS.

Appendix 3:  JunoCam at perijove-1: a global survey of Jupiter in 2016 August.
