Assembling data from 5-6-7 January methane sessions I was able to produce these two complete polar map projections 
(at the bottom left, the WinJupos map name gives the start/end time of the observations). 
As far as I know, this kind of map has never been made before at amateur level.
The two vortex appear remarkably different. 
The northern is less bright and shows two spiral arms consistent with a counterclockwise (prograde) rotation. 
The southern vortex is much brighter, with an indented, irregular rim."
