On day 3 September from 4.44 to 6.30 Jupiter will be without satellites. Io will be occulted, Europa and Ganymede will be in transit and Callisto will be eclipsed. www.pierpaoloricci.it/dati/giovesenzasat_eng.htm
Bit of a disappointment. For me, moons going across Jupiter's expanse are what is worth watching. Galileo's telescope which he used to see the four largest moons was just 40x magnification.
