    I was out with my 127mm Mak-Cass around 18.13 on the evening of November 13 when I decided to observe Jupiter. I was intrigued to see not the familiar four Galilean moons but five! There they were, strung out in a near perfect line, two moons to the east of Jupiter and three to the west. Fascinating.

    Obviously, it wasn’t a new moon.

    But 45 Cap did a great job masquerading as a moon. At mag. 5.95 it fitted well with Ganymede (5.13), Io (5.65), Europa (5.72) and Callisto (6.43), and the alignment was near perfect.

    If only I had obtained an image. But at the vital moment my camera refused to co-operate. On such chance events are scientific reputations made and lost.

    Still, not long until Christmas!

    You had me excited for a moment.

    Amateurs have discovered Jovian satellites in archival data.

    Sorry! Me too. But even as a chance alignment, it was something I hadn’t seen before and very convincing.

    I can still dream.
