On August 22nd 1867, John Joynson at Waterloo near
Liverpool observed Jupiter with no satellites visible. This was done
using a 6 inch Thomas Cooke & Sons telescope.
According to Stellarium, that would have been on the evening of 21st August rather than on 22nd. Between 10:06 pm and 11:41, 3 of the Satellites (Io, Ganymede and Callisto) would have been transiting the planet, while Europa was occulted behind Jupiter
