The process of a Solar System object (planet or moon) passing in front of a star is called a stellar occultation. When a stellar occultation involves a planet or moon with an atmosphere, the atmosphere bends the light. The patterns of the bent light are dependent on the wind speeds present in the atmosphere. We present data from a stellar occultation by Titan, a Saturnian moon with a dense atmosphere. We show that the bent light patterns suggest stronger winds in the southern hemisphere. This finding helps us understand seasonal patterns on Titan.
