Voyager 2 wide-angle camera image of Jupiter and the 250 x 150 x 125 km irregular moon Amalthea. This color image set was taken on July 9, 1979 at 1900UT, near Voyager 2's closest approach to both Amalthea and Jupiter. At this time, Amalthea was located approximately 572,000 km from Voyager 2. This was a serendipitous observation of Amalthea, although the spacecraft intentionally targeted the moon for imaging during closest approach (~560,000 km) about 20 minutes later.
This image was constructed using an OGV color filter trio taken over the span of 5 minutes. This picture has been enlarged by 2x and sharpened.
