Abrupt course correctionI spotted this object while stargazing at my home, in the Noordhoek valley which is sheltered from city light pollution.I mistook the object for a satellite but noticed it was slightly larger or dimmer than a satellite, though it had the absolutely smooth and constant movement of such.The object appeared to be yellowish gradiented to white in colour and was in the shape of an ovoid with short stubby wings that protrude from the sides, the same width of the craft, with the front and back edges lining up with the nose and tail of the craft. Like an egg with stubby wings that join along the total length of the body.The object continued on a linear path for +- 4 seconds after I spotted it and then abruptly and immediately made a -50 degree course correction, as if it had no inertia, and faded from view in about a second.
