This image was taken by the MOC at 00:52:47 UT on 14 April 1993.  It
contains a portion of the disk of Jupiter and the two satellites
Europa and Ganymede.  The planet and satellites are somewhat blurred
because the MOC was still being focused (via its active focus control
heaters) at this time.

Like all images taken before the far-encounter images of Mars, this
image was taken when Jupiter happened to pass through the MOC field of
view as the spacecraft rotated in its cruise configuration, with the
high-gain antenna pointed at Earth.  This resulted in fairly narrow
time windows when specific targets could be imaged; Jupiter was just
exiting the field of view of the MOC when this image was taken.
