The two photos above feature the conjunction and occultation of Jupiter and the Moon as viewed in the early morning of July 15, 2012. The upper photo was taken just prior to the occultation from Caen, France and shows the Galilean Moons, from left to right, Callisto, Ganymede, Io and Europa (click on the photo to better see these Moons). The lower photo was taken from Corfu, Greece. It shows Jupiter as it begins its occultation behind the waning crescent. Io and Europa are trailing and soon disappeared behind our lone Moon. Mare Crisium, on the Moon’s eastern quadrant, is the lunar surface feature nearest Jupiter.
