During detailed analysis of Voyager 2 pictures of the Jupiter ring, a starlike object was identified in the plane of the ring. The same object was subsequently found on a higher-resolution frame and proved to be a satellite of Jupiter. This satellite has a circular orbit whose radius is 1.8 Jupiter radii, a period of 7 hours and 8 minutes, and a diameter of less than 40 kilometers. It is located at the outer edge of the Jupiter ring. 
1979J2: The Discovery of a Previously Unknown Jovian Satellite.
TLDR
During a detailed examination of imaging data taken by the Voyager 1 spacecraft within 4.5 hours of its closest approach to Jupiter, a shadow-like image was observed on the bright disk of the planet in two consecutive wide-angle frames, proving that it was not an atmospheric feature, and showing that it could not have been a shadow of any satellite known at the time.

1979J3: Discovery of a Previously Unknown Satellite of Jupiter.
TLDR
During a detailed search of Voyager 1 frames for additional observations of the satellite 1979J1, two small dark spots were observed in transit in several consecutive wide-angle frames of the Jovian atmosphere, proving that this satellite would have been occulted by Jupiter at the times of the Voyager 2 images of1979J1 and was, therefore, a new satellite.

Ground-based observations of the Jovian ring and inner satellites☆
Abstract Ground-based 0.9-μm observations of the Jovian ring and inner satellites are reported. The ring observations substantially confirm those obtained by the Voyager spacecraft. The firstExpand
The inner satellites of Jupiter
The Jupiter moon Amalthea and the smaller satellites J1, J2, and J3, discovered by Voyagers 1 and 2, are discussed under the collective appellation of 'inner satellites', which distinguishes themExpand
Observations of the Jovian Ring and Small Satellites
Abstract On 3 December 1988 we obtained 119 images of the Jovian ring, using the Caltech Cassegrain infrared camera at a wavelenght of 2.2 μm. The ring is seen at a near-maximum opening angle of 3.2°Expand
The dynamics of close planetary satellites and rings
The observational history and the evolving dynamical theories are reviewed for the rings of Saturn, Uranus, and Jupiter with particular emphasis on very recent results from the Voyager spaceExpand
Alfvén drag for satellites orbiting in Jupiter's plasmasphere
Abstract According to a mechanism discovered by S. D. Drell, H. M. Foley, and M. A. Ruderman ((1965). J. Geophys. Res. 70 , 3131–3145), a satellite orbiting around a planet having a strong magneticExpand
Dust in jupiter's magnetosphere: Origin of the ring
Abstract A model for the production of the Jovian ring is proposed. The ‘visible’ ring particles are micron-sized and produced by erosive collisions between an assumed population of km-sized parentExpand
Review of the Dynamics of Satellites and Planetary Rings
Some of the new discoveries and theoretical work of the most recent few years are reviewed. Many new satellites have been discovered in the systems of Jupiter and Saturn, and the planets Jupiter,Expand
Determination of the orbits of inner Jupiter satellites
Some problems in determining the orbits of inner satellites associated with the complex behavior of the target function, which is strongly ravine and which possesses multiple minima in the case ofExpand
