Zitat von
http://webservices.esa.int/page.php?id=37820"When approaching the Earth, Rosetta is a small light point ca. 18 mag in brightness, in the constellation Lynx, north of Cancer, visible from the complete planet except Antarctica. Amateur astronomers with at least a 20 cm telescope and a CCD camera will be able to image the spacecraft as it approaches."
