The Radio Science Subsystem (RSS) observes atmospheric and ionospheric occultations during this Titan flyby. This is the first near-equatorial RSS occultation in the mission. The Ultraviolet Imaging Spectrograph (UVIS) watches Titan occult the star Alpha Eri. Earlier, RADAR gets good northern polar coverage, helping to fill in a gap in the brightness temperature map.
