Schematic geometry (not to scale), with north up and east to the left. The projected spin axis is indicated in the sunward direction (PA  =  110°) and antisunward direction (PA  =  290°). Mean jet PAs and measured PA oscillation half-amplitudes are as follows: Jet 1, 55° ± 12﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩8; Jet 2 (antisunward), 290° ± 20°; Jet 3, 170° ± 12﹩\mathop{.}\limits^{{\unicode{x000b0}}}﹩6. The scheme shows the antisunward jet at PA = 290° wobbling with a period of 7.2 hr, which is also dominant in the photometric variation.
