Fomalhaut (HD 216956) is a young (100 Myr) A4V star 7.7 pc from the Sun that harbors a dusty debris belt. An exoplanet candidate, Fomalhaut b, was discovered in optical data obtained with the Hubble Space Telescope in 2004 and 2006 using the Advanced Camera for Surveys. Here we show new broad-band optical coronagraphic imaging of the Fomalhaut system using the Space Telescope Imaging Spectrograph. We recover Fomalhaut b approximately 0.5 arcsec north of its 2006 position. The new data are consistent with a bound Keplerian orbit nested within the belt.
