Hello all, The autokinetic illusion is generally described as the illusion of a _fixed_ light moving when gazed at steadily against a dark background. However, I regularly receive reports from members of the public who appear to have observed a passing satellite (often the ISS) at night, but who are reporting strange (impossible) non-linear movements of the satellite. E.g. jumping back and forth and zizagging along the track. Since the autokinetic illusion is generally associated with _motionless_ light sources, I would be pleased to hear if any of you knows of any information or articles on autokinetic illusions and _moving_ targets, such as satellites. Many thanks in advance for your suggestions. Best wishes, Frits Westra ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
