Summary
This report covers Jupiter from 2012 Aug. to Dec., and follows on from our
previous reports nos.3 and 6. During this period, the planet's appearance
has become more normal after the drama of the NEB and NTB Revivals, but there is
still much complex activity in those regions, and reddish colour is still
widespread across the NTB(S), NEB, and parts of EZ. The NNTB is still
absent but we are able to trace the long-lived ovals in the NNTZ, whose recent
history is summarised in Appendix 1. The conjunction of the increasingly red GRS
with the very red oval BA has also produced a striking appearance.
Along with this report are six Appendices giving further details:
Appendix 1: NNTZ: Anticyclonic ovals, 2008-2012 (Gianluigi Adamoli &
John Rogers)
Appendix 2: NEBn: Dynamic interactions of spots
Appendix 3: Equatorial Band: Tracking the f. end
Appendix 4: SEBn: A new South Equatorial Disturbance?
Appendix 5: Zonal wind profiles (Grischa Hahn)
Appendix 6: Fireballs on Jupiter (Dr Ricardo Hueso)
