On 7 June 1972 the third , Jovian satellite Ganymede occulted the eighth-magnitude star SAO 186800. Successful photoelectric observations obtained at Lembang, Java (Indonesia), and Kavalur, India, show nonabrupt immersions and emersions, indicating the presence of an atmosphere whose surface pressure is greater than about 10-3 millibar. By fitting the two occultation durations as chords to a model disk, the diameter is found to be 5270 (+30, -∼200) kilometers, the major error contribution… Expand
Observations of Ganymede, Callisto, Ceres, Uranus, and Neptune at 3.33 mm wavelength
Abstract We have measured the 3.33 mm wavelength disk brightness temperatures of Ganymede (136 ± 21°K), Callisto (95 ± 17°K), Ceres (137 ± 25°K), Uranus (125 ± 9°K), and Neptune (126 ± 9°K). OurExpand
New Observations of Surface Markings on Jupiter's Satellites
Abstract Visual and photographic observations of the Galilean satellites of Jupiter made in September 1973 with the 108 cm reflector at Pic-du-Midi Observatory are presented. A method of estimatingExpand

Implications of Jupiter's Early Contraction History for the Composition of the Galilean Satellites
Abstract Graboske et al. (1973) have shown that Jupiter's luminosity was orders of magnitude larger during its initial contraction phase than it is today. As a result, during Jupiter's earliestExpand
The Galilean satellites as a source of CO in the Jovian upper atmosphere
Material from the Galilean satellites of Jupiter ejected by energetic particles in the Jovian magnetosphere may provide large sources of oxygen to the parent planet. Formation of a CO molecule is theExpand
The occultation of κ geminorum by Eros
Abstract The predictions and observations of the occultation of κ Gem by Eros on January 24, 1975, are described. At least eight positive and several critical negative observations were made inExpand
Europan surface phenomena
Abstract The interaction of corotating iogenic plasma with the surface of Europa in light of recent ice sputtering, experimental results, and published Voyager data has been examined. It has beenExpand
Is Radiolysis of Ice the Source of Oxygen ?
Although it was expected that oxygen, a product of the dissociation of water, exists in thin atmospheres around icy satellites [Yung and McElroy, 1977], the discovery of condensed oxygen on GanymedeExpand
First stellar occultation by the Galilean moon Europa and upcoming events between 2019 and 2021
Context. Bright stellar positions are now known with an uncertainty below 1 mas thanks to Gaia DR2. Between 2019-2020, the Galactic plane will be the background of Jupiter. The dense stellarExpand

Frequencies of Occultations of Stars by Planets, Satellites, and Asteroids
TLDR
A systematic program of occultation predictions and observations is urged to improve knowledge about the atmospheres, sizes, shapes, topography, and positions of these poorly understood bodies, in support of forthcoming spacecraft missions to the outer solar system. Expand
