Earth Wobble?

While the FY2D animation on SSEC appears to depict a consistent wobble pattern, it only displays images taken every hour within a 7-hour window. Above is an animated 24-hr compilation of these images. Although the Figure 8 Pattern is not entirely obvious from this perspective, the push on the N. Pole when the Sun is rising over the Pacific at 18:30 UTC is quite evident, as well as the rebound 12 hours later at 06:30 UTC. The sudden cloud cover change at 10:30 UTC is due to the animation starting over again, returning to the beginning of the loop.
