WE report results from the first stellar occultation by Titan ever observed. As predicted by Wasserman1, on 3 July 1989 the bright star 28 Sagittarii (visual magnitude, V ≈ 5.5), passed behind Saturn's giant moon ( V ≈ 8.3), which is the only body in the Solar System that, like the Earth, has a dense, nitrogen-rich atmosphere2. The event, visible from Europe, North Africa and the Middle East, allowed us to probe Titan's atmosphere in an altitude range of ∼ 250–500 km (a pressure range of ∼250-1… 
Probing Titan's Atmosphere with the 1995 August Stellar Occultation
Abstract On 1995 August 21, Saturn's moon Titan occulted the 13th magnitude star GSC5254-00997. The predawn event was observed at 2.3 μm with the NASA 3.0-m Infrared Telescope Facility. We measured
Structure of Saturn's mesosphere from the 28 Sgr occultations
Abstract We analyze an extensive data set of immersion and emersion lightcurves of the occultation of 28 Sgr by Saturn's atmosphere on 3 July 1989. The data give profiles of number density as a
Stellar Occultation Saturn ' s Upper Observations of Atmosphere by Asantha Roshan Cooray
We have analyzed three stellar occultation observations of Saturn's upper atmosphere during the years 1989 to 1995. These occultations probed the stratosphere at pressure levels about 0.5 to 20
A review of Titan’s atmospheric phenomena
Saturn’s satellite Titan is a particularly interesting body in our solar system. It is the only satellite with a dense atmosphere, which is primarily made of nitrogen and methane. It harbours an
Results for Titan's atmosphere from its occultation of 28 Sagittarii
ON 3 July 1989 the bright K giant star 28 Sgr was occulted by Saturn's largest moon, Titan. This event, which was predicted by Wasserman1, offered a unique opportunity to probe Titan's extensive
Occultation of stars in the UV: Study of the atmosphere of Mars
The stellar occultation technique permits effective sounding of a tenuous planetary atmosphere, such as the atmosphere of Mars. On the basis of measuring characteristics of the SPICAM Light UV

Abstract Stellar occultations by solar system objects allow kilometric accuracy, permit the detection of tenuous atmospheres (at nbar level), and the discovery of rings. The main limitation was the
The Structure of Titan's Stratosphere from the 28 Sgr Occultation
Abstract A dozen lightcurves obtrained during the ground-based observations of the occulation of 28 Sgr by Titan (3 July 1989) are reanalyzed. Profiles of density and temperature between altitude
Analysis of Light Curves from the 2003 Nov 14 Occultation by Titan of TYC 1343-1865-1
We observed a stellar occultation by Titan on 2003 November 14 from La Palma Observatory using ULTRACAM with three Sloan filters: u', g', and i' (358, 487, and 758 nm, respectively). The occultation

Infrared observations of the saturnian system from voyager 1.
TLDR
During the passage of Voyager 1 through the Saturn system, the infrared instrument acquired spectral and radiometric data on Saturn, the rings, and Titan and other satellites, implying a depletion of helium in the atmosphere of Saturn relative to that of Jupiter.
