Light and Shadow in Jupiter's Moon System
A mutual occultation of two iovian moons occurred ob Feb. 12, 2015: Io (the innermost of the Galilean satellites) occulted Ganymede, the largest of all moons in the solar system. Colleagues Hans Kirch and Georg Görgen had a 12" Newtonian and a ASI 120MM video camera equipped with a Planet Pro IR-pass filter at their disposal to record the event.
Despite poor seeing conditions, they managed to image the passing of Io and its shadow before Ganymede.
