On February 27, 1979 Voyager 1 approached Jupiter and captured this double transit of Jupiter by moons Io and Europa. This photo was created from a 14-frame mosaic. Most of the data was captured in a 3-by-3 mosaic at around 11:00 on February 27, 1979, but gaps were filled with data taken an hour before and an hour later.
