Jupiter is in opposition at the moment (closest approach to the Earth is today). When I was young I was interested in astronomy, and a friend of my parents back in Perth in the 1960s had exceptionally good eyesight - when Jupiter
was in opposition she could see the Galilean moons with the naked eye. If I was out in the backyard with a pair of binoculars, with no visual aids she could tell me where each moon was - closest moon at five o'clock, another one further out at eight o'clock,
etc.

On the evening dog walk on Rocky Knob I came across a man with a camera waiting to photograph Jupiter which had just appeared to the south-east in the pale sky, resembling the lights of an aircraft frozen on its approach
to Canberra Airport. He said it was unusually close. So alerted, I took a photo myself later. Four moons are visible, as they are through binoculars.
