I updated RSS and RO earlier through CKAN, and now my geostationary satellites have an orbital period of 9d, 23h, 58m. I'm not sure how this 9h got added to the orbit, as they're still circular at 35,786km. The Earth below them is also spinning, and not still. (as seen when I warp) From the space center, warping from sunrise to sunrise takes 24h.
